Best thing about D2 now is unless your computer is more than a decade old, it should run it just fine.
The closest game to how D3 looks on the gameplay vids right now is Titan Quest (and its expansion, Immortal Throne). Top-down view, pretty 3D graphics, random drops, ect. TQ is what I'm playing now. :/
... I'd ask if you guys are looking forward to any other games, but I think I'll start a new thread for that. :P
