okok...
first of all, get the hell off Bulletstorm's back!~ I enjoyed that game, it's fun, so STFU!
Second... Kids are NOT supposed to watch/play M-rated games! this is NOT the creator's(developer, artists)fault! it's like telling us "Hey! Hentai anime/game/manga are evil! they will turn our young children in to rapist! Therefor they should get banned!" well... these things are NOT made for kids! they are made for US! damn, shut the hell up already! blame the (retarded) "not ready parents", "money comes before moral" game shops, and stupid "we sell M-for teens games" (AKA"your mom will hate it" ADs from stupid companies that decided that it was funny to make it look like they are selling to kids...)
Third, it's okay to be desensitized, it's better than going insane the first time you see a dead person, leaving a scar for life, right? "violence? no consequences?" this is actually being adjusted in the games now, with the implemented "moral systems", "karma", good/evil meter...etc for more immerse experiences... Choice/Rewards should always go with the model: good people suffers, and have to work harder, bad people finds easy answers to overcome short-term problems, the end, good people will receive grace, will bad, will have to pay their dues...(each situations differs)
Fourth, violent video games don't promote violence! I played Duke Nukem when I was like 14!!! I played countless violence games prior to that one earlier! but in real life, I am a passive; I was Considered as nerd, geek, easy going, and perhaps easy target for bullying! by Chinese FOBS! I was taller than 80% of the people in my school, and yet, other than a few "nerd rage", I have nothing more than grade issues as school problem! (of corse, I haven't played "manhunt", but played mad-world/condammed/bullet storm, DeadSpace1/2 ..and such to the death!)
Fifth, I didn't get more violence, but my literature did suffer dramatically! I notice how much my vocabulary of English had becoming limited, and how my profanities had increased, not just the knowledge (or pile), but the frequency as well! BY A LOT~ it's the mind set, I am now trying to "fix" this issue by playing games such as "dragon age", to experience some thing less "Bulletstorm-y" so next time I speak to a (because I works at an after school) kid, I don't spam "shit", "dick" or "fuck"... (not that it happened...yet...I could soooo get fired for bad word usage...), yeh, this is the only problem i see so far, and I DO hope the future game dev, and script writers can take more creative approach than the shock factors of the word "FUCK" to show character, maybe this is a good topic for "extracreditz" episodes, the episode where they can talk about "language in games"!
