Guts would never willingly play videos games in his entire life, which is why I am blessed eternally for his AU self not being such a stick in the mud and letting him actually enjoy things.

Guts is a hardcore Yoshi fan. He picks Yoshi every chance he gets, and then plays like an utter maniac for the rest of the game. Probably the guy who ragequits halfway through any play session, even if he's winning.
