Yeah Ocarina of Time definitely is one of my all-time favourites aswell.
One of the main reasons to get the Switch would be Zelda and Mario Kart to be honest :D we'll see if the price drops at least a bit before I decide to get it.

Other than that I'm actually not that much into shooter but I really enjoyed CoD4.
I really played too many games to just call a few favourites... you probably know that feeling :D
