And it's for a fantasy setting (surprise!).
Well, for starters I'm a complete newbie here, so hi everybody (and hopefully this is the right place to be posting this stuff)^^
I've played a few role-playing games in the past, though not many. I have most experience in the Star Wars Saga Edition game (GMing & playing), a little in D&D 3.5 and 4E (GMing in 4E only).
The intention of this project is to design a fairly rules-lite system for most any fantasy role-playing game, with an extensive list of skills and a classless set-up.
I also plan to write a simple setting that I hope to establish later, though I want the mechanics down first.
You have a basic array of attributes (Strength, Dexterity, Constitution, Intelligence, Wisdom, Charisma, and Luck), a skill list, and equipment slots. Like in fallout 1 and 2, skills will have a base value determined by simple mathematics (attribute A + (/2 of attribute B) for example).
Then each skill has ranks; you can buy up ranks with Skill Points (SP), and depending on the skill it will increase a set amount per rank. For example, a skill increases by 3 points per bought rank, and the character in question has 2 ranks, they have rating 6 (plus their base) in that skill. Then equipment may also change your total skill rating.
So a complete example of a skill would be:
(attribute A 1 + (/2 of attribute B)) + (Increase per rank x rank) + equipment bonus = total.
I'm also considering the usual defences as skills, rather than derived stats. So Reflex, Fortitude, Will, or whatever the finalized defences are, they can be specialized in via skill training. And because each skill has a different base calculation and increase per rank, I can scale them appropriately.
So far, I think the percentile system (2d10) would be best suited for the skill set-up; otherwise it may need a significant amount of dice (or a few big ones, like 2d20) to keep some element of chance considering the changers per level with the few experiments I've done. Having said that, how much should it be down to chance?
Any thoughts on what I've brainstormed so far?
