Graphically, Uncharted 4... naturally.
Zelda U can look really beautiful though.
But there's no point of comparison here, both games aim for diffeent things.
My bet with The_Liquid_Laser: I think the Switch won't surpass the PS2 as the best selling system of all time. If it does, I'll play a game of a list that The_Liquid_Laser will provide, I will have to play it for 50 hours or complete it, whatever comes first.
