Ooooooooh, I like this one. Top five games, no particular order:
-Borderlands (1, 2, 3, but not so much the Pre-Sequel)
-Halo (usually replay the third one, nostalgic game for me)
-COD: Modern Warfare 2
-Spore (I've lost days playing this dumbass game, and it never stops me from doing it again)
-I want to say Guitar Hero just so I can brag about how obscenely good at it I am at shredding on that plastic ax, so I will.
Also in the rotation is Rocket League (I'll hop on the phone with my buddy and play together while we shoot the shit and call each other fags or whatever), I had a Sim/Civ/Zoo Tycoon problem for a while... And I have a few dozen games on Steam that I've burned an afternoon or eight on. Oh, and Red Dead. Oh fuck, and then there's all the N64 games! Golden Eye and Perfect Dark and Bango Kazooie and Mario Kart, Donkey Kong, Zelda... fuck.
Consoles? Less picky about. I have a good collection of Playstations (1, 3, 4), Xbox/Xbox 360, N64, PC, I haven't messed with the Switch but I imagine he's pretty great. A couple NDSs. They tend to accumulate over time, and I give them a good home.
Phew.
