I'll bite for the Grim Dawn. Looks like fun.
Mordheim is pretty awesome. I've got about 200 hours in and I'd highly recommend it. It is a time commitment though. I can't get Xova to play MP with me because the matches take a good 1-2hours+ (if you don't put in turn timers). It is tough, especially at the beginning. If you are fan of playing XCOM in ironman, then this game will fit.
