Xenoblade X: Every time I had thought I'd seen it all in this game, there was another secret area, or another level of customization I've never even began to touch. The world with no loading screens is nothing short of one of the most impressive things I've seen in a long, long time. Also I felt very satisfied with the story as a part 1 in a series, which it will no doubt be. World building that simply cannot be touched. 10/10, will buy the sequel day 1. Worth buying a console for.
Bayonetta 2: Easily the most fun I've had in YEARS. Where Xenoblade is about putting the player through a variety of emotions I played this game with a smile on my face the whole time. It's controls and combat system are perfection, It's characters are fun and goofy and you love to be around them. It also visually looks like the best game on Wii U IMO, besides maybe Sm4sh.
Sm4sh: The roster, the online, the visuals, the frame rate. It's easily the best fighter this gen, I don't feel I need to get into this one.
