My beef with the series is that I literally cannot play them.
I got MvC3 day 1, and I spent hours practicing my combos in the training room and playing through Arcade Mode with various characters.
Then the first time I played another person, I barely got a hit in because all the chaos on screen was so distracting and he was able to take out each of my 3 characters with like 2 combos each. It was the most frustrating defeat in my history of playing video games, and I realized that I am literally incapable of playing this series. I legitimately don't understand how anybody can play the game without like 500 hours of committing combos to muscle memory and also the reflexes of the fucking Flash.
Whereas with Injustice, I was able to actually get somewhat competent.
So that's why I say, "I want Injustice with Marvel characters," and not, "I want Marvel Super Heroes 2." I'd prefer it not be made by Capcom at all, really, as I think a lot of Capcom's move sets for Marvel characters are stupid and I'd rather see these characters redesigned from the ground up with a fresh perspective than made by people who feel obligated to use existing move sets just because they're 20 years old.
