While there haven’t been really any heavy-hitting fighting games like Mortal Kombat or Street Fighter (a new Street Fighter anyway) there were a lot of great lesser-known fighters this year.
Super Smash Bros. For Wii U
It shouldn’t surprise anyone that SSB won this year. While the other fighters are great they are more of what we have seen from those franchises already. SSB continues to improve on the already loved formula with more characters and tons of recognizable content that re-ignites memories from our childhood and past and nothing can top that feeling.

Yep! The fact that I forgot about this game until you made a comment proves that.
