Killer Instinct - What a comeback this fighter made in 2013. Killer Instinct stands as one of the best Xbox One launch games and also one of the best fighting games (besides Injustice: Gods Among Us, of course). The revamped character design and the heavy focus on combo mechanics manged to turn this fighter into one of the best multiplayer experiences of the year. Welcome back, Jago! We missed you (same for you, Sabrewulf).
