Opposed Rolls

November 12, 2011 /

Before going into a post likely to be snored off, I wanted to thank Kevin Sullivan for the stats he generated on this site. The presentation of certain things are more clear there. He also provided me with a good idea on how to generate Class XP tables for Andras.

I had posted on Google Plus about a shortcut method of performing opposed rolls. The numbers do not come out the same, but I figured that they were close enough. What I discovered in studying these numbers points to effects of specific designs. In the end, I think that my design doesn't produce results that are always similar, but that produces results more in line with my design philosophy.

Specifically, the results show that:

  • Characters with equal bonuses to skill rolls under Microlite20 will have a similar, but varied chances of success under my system.
  • The Microlite20 system is affected by relative adjustments to the roll. My system is affected by the actual skill ranks and Attribute score.

Here is an example using the Microlite20 rules as written and comparing to my system.

Listen is Subterfuge + MIND.
Move Silently is Subterfuge + DEX

Aesir is attempting to sneak up on a guard. Aesir has a 16 DEX and a Subterfuge rank of 2. The Guard has a MIND of 12 and a Subterfuge rank of 4. According to the rules, the one with the highest roll wins. Each character receives a bonus to their individual rolls of Skill Rank + Attribute Bonus.

For Aesir, we get 2 (skill rank) plus 3 (Attribute Bonus in M20) to get 5.
For the guard, we get 4 (skill rank) plus 1 (Attribute Bonus in M20) to get 5.

Given these stats, Aesir will succeed 47.5% of the time. The guard will succeed 52.5% of the time because he will win all ties. By rule, ties go to the character with the highest skill rank.

Under the Microlite20 system, the chances of success will not change if the guard has a Skill Rank of 5 and a MIND of 10, a Skill Rank of 3 and a MIND of 14 or a Skill Rank of 2 and a MIND of 16. The adjustment to the roll remains +5.

In my system, success is determined by rolling-under the total of the Skill Rank and the Attribute itself. When performing an opposed roll, the Player Character has to subtract half the total of the NPC's skill rank and attribute. In this example, Aesir's Subterfuge rank plus DEX is 18. The guard's Subterfuge rank plus MIND is 16. Success is determined by Aesir rolling equal to or under 10. In other words, 18 minus 8 (half of 16). This give Aesir a 50% chance of succeeding. This is a slightly better chance of succeeding than with the Microlite20 system.

What I found surprising is that if the guard is changed as I mentioned earlier, Aesir's chances of success are affected.

sub MIND Aesir Wins
Guard 1 5 10 52.50%
Guard 2 4 12 50.00%
Guard 3 3 14 47.50%
Guard 4 2 16 45.00%

All four of these guards are identical according to the Microlite20 system, but the results are slightly different under my system. Nothing is really dramatic in the results, even with very improbable NPCs (do you hire MIND 16 guards? Would a MIND 10 guard have a 5 subterfuge skill?)

For the sake of completeness, let's say that Aesir is opposing a lower skilled guard of average intelligence. Subterfuge skill rank of 2 and a MIND of 10. Under the standard Microlite20 system, Aesir has a 62.5% chance of success. Ties no longer go to the guard, but they don't go to Aesir either because there would be a re-roll. Under my system, Aesir has a 60% chance to succeed.

Why does it give a worse chance? The amount of change is less in my system. If you compare the original example, Microlite20 provided no advantage to Aesir. He and the guard were equal. In my system Aesir had a slight advantage, thus a higher chance for success as compared to M20.

Changing to scores provided Aesir a great advantage. Instead of being even with the Guard, he now enjoys a +3 advantage. That big of an advantage yields bigger results. In my system, Aesir already had an advantage over the first guard. Changing the skill and MIND score had less effect because the amount of advantage changed comparatively less.

Somehow I'm Awake, What Does All This Mean?

Advancement in Microlite20 provides for increasing Skill Ranks and Attributes. This makes the characters very high powered around 10th level. In my variation of M20, characters cannot change Attributes except by magic or optionally by age.

I hope this means that characters can be fun to play for more than 10 levels.

This also means that using Microlite20 as a platform to develop Andras helps me get the bones of the system working well. This will be easier to playtest, especially for newer GMs. This also allows me to playtest a solo version of M2010 (my system). Maybe I have been reading too much T&T lately, but having a solo version plus the Mythic GM appeals to me.

As always, more later.

A Different Division of Rulebooks

November 5, 2011 /

I posted about this in G+, but wanted to expand on the thoughts here.

It starts with this post from Greywulf.

The shared worlds thing was already done with Spelljammer. As I said in G+, Dragon Magazine even had an article for porting over Space:1889.

As far as writing style, I am all over the end to the Gamebooks are Technical Manuals school of thought. Even the rules to Life (boardgame) are not as dry as other game rules.

I don't like to use minis, so I'm just skipping that part.

I wanted to focus on the bit about doing this with an OGL game like Labyrinth Lord. To do one better in this exercise, why not just go straight to Microlite 20. One page of rules, many possibilities, right? Well, let's start with M20 Purest Essence. 17 pages.

The PHB: Remove all race and class information and the Game Master's Guide. Also remove the spell lists and the creature lists. What you're left with is about one page of rules to play the game.

The GMG: The entire M20 Purest Essence, although it will need to be organized.

Then we have the codices:

Humans - Race information for humans (+1 to all skills). Class information for all humans playing the various classes.  Add the spell lists, but make them different in flavor and selection. The only place with a universal spell list is the GMG. That's just the crunchy stuff. The rest is history, a section like the Roman Way called the Human way. Outposts of humans in various game worlds, etc. Art, fluff, lots of stuff.

Elves - Race information for Elves (+2 MIND). Class information for all elves playing the various classes. Add the spell lists, but make them different in flavor and selection. You see where I'm going.

At the table, the player has a codex and a one page handout for rules. The GM has the GM Guide.

What do you think?

A Project Begins that Probably Shouldn’t

May 15, 2010 /

The ill-advised retro-clone is under development. Unlike the misfire with combining the Fantasy Trip and M20, this project is actually gaining steam. I've developed my own "Appendix N" of influences on the game.

Why?

The main reason is that I house-rule just about every retro-clone I try. It's not that I don't like the system at all, it's just that I have a 'kitchen sink' mentality to what is included in games I run. For example, I love Spelljammer and Mystara. Both have flying airships and interplanetary travel. (Granted, you can only get to the moon in Mystara.) Looking at rules for aerial combat in various games, I rarely find any that are really straightforward that allow the player some diverse options. This generates a set of house rules for aerial combat. Once the rules for it are generated, I think about a class that specialized in it. That generates more house rules. Then I think about aerial travel over long distances, life on an aerial craft, fresh air for interplanetary travels, etc. More house rules and bolt-ons.

This is the way my first group played and I've never gotten far from it. You want lasers? Okay. Flintlocks and Aliens? No problem. A class of adventurers that use origami creatures to do its bidding? Sure, here's the XP chart.

I came this close to calling the system "Pocket Dragons & Pomegranates"

I abhor combat that takes 30 minutes for an encounter. I value combat, but not the feeling that a group of me and my friends are wading through layers of rules and charts. It's an element of the story. It could even be the focus of the story. Still, I award XP for good role-playing, treasure, innovative tactics, etc. Players wringing the rules for every ounce of advantage is just not for me, though I don't penalize for it. I have to admit that a couple times, this type of play generated some very unusual play that was fun  for everyone.

The real reason, though, is that I want to put together all the things my first group and I did into one cohesive whole. It's not easy, due in part to a lack of concern for contradiction. We just called it "gamer's paradox" and let conflicting rules lie. This time, I don't want a paradox, but I want largely cohesive system.

Having said all that, here's an sketch of what I imagine the system to be:

  • B/X and BECMI based with a mixture of M20, 1e and 2e.
  • Simple mechanics with lots of charts.
  • Build systems for new and existing classes, monsters, and races.
  • Race and class are separated.
  • Rules for adventuring in any locale (air, water, planes, ether, planets)

That says a lot, so here's a few specifics in no particular order. No THAC0 despite my love for it. No 2e style kits, at least not intentionally. I hope to achieve so-called game balance by XP, not by making everyone equal in power. I don't want to re-create a HERO system style build process for everything. I'll use BAB like Basic Fantasy does. There will be an optional silver-based economy set of rules. Lots of creatures, but not at the cost of making them look like they were created in a random generator. Yes, psionics, but using what I believe to be a non-traditional system.

In short, it will be a kit and a rudimentary setting ready for use. Folks will be able to pick and choose what rules they want to use, and what rules they want to discard.

As an added bonus, I hope to use Dokuwiki and the bookcreator plugin to allow individual players to download a customized ruleset. The layout may not be perfect and there may be a couple odd page-breaks, but it should work.

The class generator is complete. The monster generator only creates low-level creatures so far. True to my old school roots, they live as spreadsheets at the moment.

Otherwise, I can only say that I am fully aware that this is largely a vanity project. I have no illusions of 'energizing the OSR market' or being the next LL. More than anything, it's a labor of love for something I loved as a kid.

Stay tuned!
