She's got a soft spot for older RPGs and is willing to try just about anything with a lovey-dovey "I can fix them" romance element.

Her weekly to-do always includes a bit of MMO time, endlessly achievement hunting and raiding in Final Fantasy 14.

Outside of those staples, she's often got a few survival-crafting games on rotation and loves a good scare in co-op horror games.
