Grand Theft Auto V is the single best looking game of it's generation, so that obviously.
Forza Horizon 1/Forza 4 and Rise of the Tomb Raider as well.
Bet with Intrinsic:
The Switch will outsell 3DS (based on VGchartz numbers), according to me, while Intrinsic thinks the opposite will hold true. One month avatar control for the loser's avatar.
