My favorite games (in no particular order):
Pokemon (the whole franchise, or most of it anyway, though my favorites are White 2 and Conquest)
Borderlands 2 (Hyped for Borderlands on the moon, it's gonna be sick)
Fire Emblem: Awakening (AKA Waifu Simulator. Planning a second playthrough but busy with other games at the moment)
Dust: An Elysian Tail (This game is the definition of eye candy.)
Terraria (Played this with a bunch of friends, something went wrong and we didn't even get to beat Plantera :c)
osu! (Duh. I see hit circles in my dreams.)
Age of Mythology (Nidhogg master race)
Civilization 5 (I've only played 100 hours of this, I need to pick it up again. Or for the sake of my social life, I probably shouldn't)
Crypt of the Necrodancer (I love the dungeon crawler/rhythm game combination.)
