The mother of all dungeon grawlers... at least it's the best one if you ask me. You can either dungeon crawl yourself, or you can do it with others in co-op, which is even more awesome. It's still one of my favorite co-op titles even though its so old, blizzard really succeeded with this.

Play as different classes with their own abilities. Crawl yourself throughout a hundreds of different dungeons and a dozen quests.
