The first response was a really good one. I play both, but mostly MvC3 since I like fast paced, intense action. A disclaimer about MvC3 though, if you get into it, it’ll be a game you LOVE but at the same time HATE. No fighting game imo will get you saltier(you might need to look up the term) than MvC3. But when it’s good, it’s real good. I personally mostly play AE to improve my fundamental skill sets for MvC3, but I’ve found it to also be a game I can really get into. For me, this is how it breaks down:
-Fast paced and intense
-Easier to get into (easy to learn day 1 abc combos)
-More of an all or nothing feel, since one hit could convert to a huge vicious combo.
-A bit random sometimes, which can be frustrating
-Flashy as hell
-Slower paced and more methodical
-More about spacing, match ups(your characters strength/weaknesses vs your opponents), mind games, footwork, etc.
-Matches feel more controlled since there’s quite a bit less randomness
Like others have said though, it’s good to play both, and there’s a good reason most of us play both. If you want to get serious in either game, playing both will improve skill sets that the other would benefit from. Marvel being the faster game would help your reactions, blocking, and quick thinking. AE would help more with strategy, spacing and reading your opponent. I’d learn the basics of both and play both. From there, you can decide what you want to main. Both are awesome and challenging games, just in different ways. It’s up to you to see which is for you.
EDIT: Btw, if you decide to get into MvC3, send me a message on here. I can send you a bunch of helpful links to get you started. I put a lot of friends onto MvC3, so I have tons of helpful links on deck.
