Mortal Kombat 1 - Back to the beginning of Boonality

Oh wow you’ve missed out. While 9 has story elements that lead into X, you can skip it. The story is gonzo enough that you’ll dive in, be lost, but catch up and just go along for the ride. Seriously, play story mode in X and 11 and just enjoy the hell out of it. Put it on easy and let it wash over you.
