Voted Mario Party, it really restored some of my faith in franchise. ND Cube's best effort yet. My friends and I had countless hours with fun it. Mario Tennis Aces was enjoyable too, The devs really nailed the Tennis gameplay this time around.
Kirby on the other hand was somehwat of a letdown compared to Robobot. For starters they shouldn't have charged full price for it. Same goes for Pokemon Lets Go.
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.
