Rezzing this thread for introspective purposes, since most of the games we all talked about have either been released or delayed, and the stuff coming out for Q4 of the year wasn't even on the radar last year as definite 2015 releases (Fallout 4, fuck yeah).
So I'm gonna take a stab at my mid-thread list:
Bloodborne: Played through this twice already. Beautifully made, fantastic--every positive thing that's said about it is true. And apparently it's changed quite a bit since the beginning of the year, so I'll have much to look forward to when the expansion comes out.
Dark Souls II: Scholar of the First Sin: Didn't enjoy this as much as I wanted to.
