Actually, those are both T. (I honestly haven't seen a fighting game in that style rated M o_O) But I'm not one for fighters. :/ Too much button mashing.
I will be sure to do that tomorrow.
Ever heard of Mortal Kombat? That's rated M. And you're not really supposed to button mash, since you'll lose most of the time if you press buttons without thinking properly on when to use them. You should just skip UMvC3 entirely, and wait for Street Fighter x Tekken. Or go for King of Fighters XIII, Super Street Fighter IV: Arcade Edition, and Mortal Kombat. If you're more of a single player guy, then you should completely avoid Capcom's fighting games since they're entirely centered around multiplayer. Fighting games like Blazblue, King of Fighters, Mortal Kombat, Tekken, etc all have dedicated single player modes (story mode, challenges, customizing, etc).
