Compbros, again, you're preaching to the choir. Between the blatant sex appeal (of underaged characters, no less) and the over the top weapon based violence I absolutely do not understand how Soul Calibur is rated anything less than Mature and has not been for years. So if you're asking me, personally, then yes both SC and Injustice are over the line. As for Deadpool? You're talking one character out of a cast of almost 40, most of which are completely tame or outwardly jokey and again, no blood. Same with wolvey, all the sword users, and a psychotic raccoon with a gun. Believe it or not, it was actually Nemesis they were the most worried about ratings wise. His level 3 super didn't fly with the board, thats why its all confusing and retarded looking. Thats how fucked up the ESRB system is. Trench coat tentacle monster = adult, totally hip gun toting swordsmen = teen.
That said, we're not talking about one move or even one character in Injustice. Everybody in this game is beating the absolute shit out of everyone else, with slow motion camera zoomey battle damagey goodness. We got Deathstroke unloading on people point blank, rocketships to the face, and Batman (the people's champion) running women down with his car. According to the edicts of modern US society, that's just the going ons of consenting super powered adults. But the second you introduce an "innocent defenseless child", its a mature situation.
And you can plainly see how retarded the double standard is, because as long as they get up and pout after getting sent through a wood chipper, its "kid friendly", but that same 13 year old won't understand why a man wouldn't get back up after being punched out of orbit.
