I think the only contender to stand against the big bad boy witcher 3 for the best game of 2015 would be MGS: Phantom Pain. This game totally kept me in awe. Kojima, I can’t tell my love for you despite what Konami did for you, you are indispensable. The gameplay. The story. The graphics. And you Snake. This game would totally hook you with it’s compelling story and the the cute dog.:P
Go for it guys. Without thinking once.
