Temple Of Osiris is much more "appropriate" for lack of a better term, if you're not playing co-op with another hardcore gamer.

Diablo 3 has been my go to local co-op game for years now. I can't even count how many times we've beaten that game from beginning to end maxing out different characters and raising the difficulty each time.
We left off on the second, or third to last torment difficulty level the last time we played.
