I have bought and/or played most of the big hits of 2015, fallout4, star wars, batman, halo5, etc. and i did enjoy them for a couple of hours, but none of these games really felt like goty material. Then Xenoblade X came out! Oh man is this game awesome, this game world has got me in like nothing else since gta3 came out. There is such a massive game world to explore, and even if wii u is underpowered compared to other consoles, its just the prettiest game world I have ever seen, the game world is like nothing else and it feels like landscape porn!! It does have a lot of flaws, like bad camera in fights, some very annoying music tracks, bad voice acting etc. The way I see it it feels like a saturday morning cartoon plot, an old TMNT show story wise and im fine with that, dont expect something too serious, the gameplay is awesome, its overwhelming at first but once you start to understand the complex menus, options, and different gameplay modes its fantastic. My GOTY: Xenoblade Chronicles X!
