Well, one of my favourites is Link from Twilight Princess... I guess I'd hide the pots, and we could go out and have a Red Potion together

Maybe beat up some goblins while we're at it...
Link from the Wind Waker could take me sailing! Awesome!
Wander from Shadow of the Colossus? We could go horse riding, do some archery or sparring, or discuss the potential for art in the beautiful game he's from... Maybe go kill the local giant stone beast
Oooh!
Mario, we could go save-a the Princess, stomp some mushrooms and turtles... But wait, I love turtles! Screw that.
Gaz?
I dunno, we could go out shooting. He would have illegal automatic firearms but it's all good!
