And thinking of it, it would also be possible to implement a xp system based on Call of Cthulhu : if you used a skill this session, you could do some kind of roll to determine how many DP you gain in that skill. Or something like that. Kinda like the stat roll. I don't know, that's just my first thoughts on this. Really chaotic. But if someone can figure something out, share it!
I mentioned this in another thread. I played a *long* time ago (almost 20 years now) with a system the GM customized for lvl development. Every time you used a skill, you rolled with some mods, and if you succeeded (i.e. 100+) you advanced the skill 1 *point* (not one rank). You were limited to the number of times you could try this roll (I think it was once a week per skill for static, unless in combat, then once per combat session). Body Development advanced the same way. If you took damage in combat or at any time (i.e. used the bodydev skill), then at the end of the combat session, you would roll to see if it advanced.
The forumula I think was:
50 + OpenEnded + StatBonus - CurrentSkill >= 100
And I think it was 50 (it might have been 100). This way, the closer and closer you got to 100, the harder it was to advance in the skill (and near impossible once you got over 100). There was skill degredation as well, if your total was less then 0, then you lost a point.
He also allowed 3 free "rolls" each ingame-month, representing things you were practicing/doing during the month that you didn't really do with the group. To keep "levels" in the game (which was needed for statgain rolls and resistance rolls) the rule was every 5 BodyDev earned was one level. The only thing I don't remember was how he handled spell lists with this system (non of us were magic users IIRC).
I'm thinking about starting a new campaign set in Tolkien's world with RMC, maybe I'll try this XP system and report back...
