At the risk of sounding completely GHEY, I admit to being somewhat obsessed in my younger years by an RPG called Shadowrun. Essentially cyberpunk crossed with fantasy. It had a classless character system which IMHO worked very well. Microsoft bought the rights and did their best to kill the concept by turning it into a FPS. It sucked. Lots. Of smelly dick.
Anyway, they’ve recently licensed the rights out to some game devs who seem to have taken the concept in the right direction.
See www.shadowrun.com for further info. It’s not THAT ghey!
