My favorite game to play while doing something else. That doesn’t seem like high praise but now that I’m done with it, I already miss it.
I would play while listening to podcast, audiobooks, watching TV shows, chatting with friends, etc. Terrific couch co-op game or to play online with friends.

Diablo 3 perfected the loot grind in a satisfying way that never wore out its welcome. Even after the Platinum trophy (which involved maxing every character), I was never tired of this game.
