I feel boring after scrolling through all the other replies and just saying Diablo 4. :p
I died against the final boss earlier this week after getting them down to a couple hits left, so I spent all week grinding renown and paragon points and just completely face rolled them this morning. Feels good, man. I can't wait to start on the endgame content.
Other than that, I played that Grimace game on my GBC style emulation handheld. It's... a game. I also played Microsoft's Bejeweled clone in the mobile Xbox app to get rewards points.
It is weird that diablo feel like you haven't really started the game until you've completed the story once. Like that whole well written story and beautiful cut scenes are in fact the prologue to the real game.
I haven't actually completed the story yet, but that's what it feels like at the moment. To be clear though - I'm really enjoying it!
