As several have said before me, being able to play a violent video game depends on your level of maturity. I play Modern Warfare 2 on a weekly basis, and have I killed a taxi driver? Not that I know of. The only ones that can't handle violent video games are the ones that begin to forget that they are playing a freaking game. Also, video games aren't all bad, seeing as they can teach strategy and hand-eye coordination. (I almost never have to look at my controller when playing video games anymore, lol.)
