To be interesting and unique, I would make humans physically superior to most other races (at least, in terms of strength). Or make it so that all of the other races have shorter lifespans, making humans the "elder race", filling the role that far too many settings default to elves.
I suppose it depends on how much you want to buck tradition.
Heh. I'm shrugging my shoulders on the whole thing of bucking tradition. The high points of my game will be the ability to write spells,(Thats what I'm working on right now.) not nessesarily it's crazy unique setting.. although I might like to have both. <:3
Current points of interest:
Determining factors on physical and mental strain regen rates, and pool sizes.
Physical is pretty straight forward, but mental is not so much.
Will HP is going to be a lot like a Will save, except coupled with a barrier of mental hit points to resist charm and fear effects and whatnot. I'm also unsure how I'm going to determine this one. Mm..
Wait. I think I have something.
oh god how did this get here
I am not good with computer
