I really disliked MK because I dislike NRS's style of combat feedback. In other words, it looks to me like the characters are pawing each other and not actually hitting each other. In MK-UMK3, when you punched someone in the face their head snapped back and the sound was right and everything felt right. After that and especially from Deadly Alliance on, the animation just hasn't felt right to me. Injustice is continuing that annoying trend.
I try nearly every fighter that comes out, but it takes a lot to keep me playing a fighting game. I also generally pick my character based on the way they look alone and if I dislike the playstyle I drop the game. Ragna, Sol Badguy, Ryu, Ryu Hayabusa, Yun Seong, Talon, Sabrewulf, Lars...I'm pretty consistent and I generally gravitate towards the main characters with a few exceptions. We'll see how this game shakes out for me.
