Decide what type of character you want to play, then go for extreems. A character with all average stats is boring! If you make a fighter make him/her very very strong and dexy, even if you have to make him an ugly idiotic fool. Other party members can fill in for a bad stat in your PC, and if you play according to his stats he will have some character. When some oarcle gives him a riddle he can ask Boo for help
I give everyone high Dex as missile weapons rule! My thieves spend most of their time hiding or invisible. They only come out of hiding to backstab.
