Diablo is super fun up to a point where the grind gets repetitive and feels like a waste of time. But that point is a different for each player. Some can play for months, some for weeks. The grind-loot ratio gets much better at the higher level torments (torment 8+, and Greater Rifts).

Odry, I still hop on Diablo 3 every now and then. Group play in D3 is definitely more fun than single player (in my opinion). Let me know if you ever feel like playing D3.

Tom Clancy's The Division looks to be very fun. So far Jay, I, Serp and Wes (cool dude from FFXIV) have pre-ordered it for PC. If you ever feel like playing that, let us know!
