is there a good rpg i can start playing right now thats as similar to diablo as possible? please recommend and describe with pros and cons of each! thanks

Torchlight.. no multiplayer, though. W8 for Torchlight II.
If you got a Dreamcast or emulator, then grab Record of Lodoss War. It's got D2 style combat, but you can customize any weapon/armor with the stats you want.

try mount&blade warband

great game.
