ZOMFG ppl, contribute!!!
i, personally, have my own idea of an RPG (MMO AND single player - no, idk if that can be done, but it will - and no, don't tell me it can't be done, let me dream on)so, ideas for your game:
Start: Obviously the present (lol). And that present should be, IMHO, for th sake of the game after a major event in your world's history. let's say rebuilding after an invasion, i dunno.
Stats: Phisyque (hope i spelled it right), Mental Acuity , Endurance (thinking of more) Charisma, Interpretation (hehe, twisting what the other says is always fun XD)
Resources: well you said you want it fantasy, so i'll put the usual ones (wood, stone, metal, food) and another 3 that are related to your game's world. Since i have no idea what you have in mind, i can't give an example.
Jobs: Merchant, Hunter, Mistic (again, i hope i spelled it right), Prior (unh... priest / prophet stuff) jeweler, woodcutter, blacksmith, artist, scribe, soldier, etc (brainstorming here XD)
Feats / abilities: wish i could help you there m8, but i dunno if i can give the type of abilities you're looking for. Maybe something like a trait system, in which you can gain various bonuses for you and your followers.
Items: (this one's hard, needs more thinking)
(will edit post later, thinking bout it)
