Taking a break from Skyrim to play Mutant Year Zero, which is more of a tactical RPG than anything. Not familiar with XCOM and the like, but I'm enjoying it so far!
It's hard but not in a demoralizing way. I like that it forces you to think about everything you have to win.
It helps that two of your party members are basically PA furries: Borman, the mutant boar and Dux, the mutant...duck.
Not the most creative naming convention, but the characters and setting are pretty cool!
