The original diablo is great, the atmosphere is so great. Even though the graphics aren't great, you are pulled into the game with the music, sound effects, lighting etc. Diablo II is great as well, I played the hell out of it, but whenever I get the diablo itch, I usually find myself going back to the original. Also, instead of going single player or creating a private b.net game, just make an ipx network game. That way you still get different premium items, elixers, and you can farm bosses for equipment every reconnect, but you don't get dropped from the server. Best way to go imo.
