I had connection issues with online matches back in 2021. I don't remember if KI 2013 has rollback but I was playing around the time I was playing a fighter that had rollback and I think I was just spoiled by how the feature made online matches smooth even when the connection weakened.
I'm sure the base single player mode is quite alright. I just don't enjoy playing many fighters offline unless I'm playing against another human player.
