I'm putting together an old-school D&D-ish hack for a game with some old friends, It borrows somewhat from Dungeon Squad and Microlite d20, but the main bit is a list of skills.
It should have ONLY things on it that are important for the average mid-level fantasy adventurer. (So, mostly dungeon stuff, some outdoors stuff - Red Box, plus a little Blue Box). It should also have EVERYTHING important for the average mid-level fantasy adventurer. There are no racial powers, no classes, no ability scores. So if its not on this list, the characters won't be able to do it.
This is the list so far. If I'm missing anything, let me know!
Arcane: Casting spells, detecting magical auras, turning undead and resisting curses.
Charisma: Haggling, commanding, giving speeches, sensing motives and making friends.
Lore: Knowing things, finding things out, monster-related facts, learning secrets, finding and disarming traps
Fighting: Smashing, punching, stabbing, shooting, blocking and murdering.
Survival: Jumping, running, climbing, tracking, carrying stuff, foraging and finding bears.
Stealth: Sneaking, hiding, stealing things, listening, picking locks and general subterfuge.
Traps: Finding, disarming and leaving traps.
