Gods Among Us
Let me preface this by saying that I am terrible at fighting games.
But I like playing them! Last week Injustice: Gods Among Us, made by the same developer as the 2011 Mortal Kombat reboot (which was a blast) came out, and man, is it a great game.
One of the biggest problems with most fighting games is the lack of balance between characters, but this is where Injustice soars. Each character is unique but some are similar, giving a nice balance but a fresh experience with each one. Only one or two characters feel slightly overpowered, but that's expected when all the others are well-matched. The best part, though, has to be the delightfully violent Supermoves.
