Well, Tom & Jerry are literally made for children... Manhunt isn't. And while kids might play these games, whose fault is that? The parents for letting it happen, or the developers for making it? Obviously, it's the parents fault. If a kid gets into his dad's gun cabinet and blows his friend's face off, or if a youngster finds a beer in the fridge and cracks it open for a drink, do we blame the guns or the booze? No, we say the parent was negligent for allowing the child to gain access to such things.
And most kids do play violent games, and they don't run around stealing cars or shooting people... it's the mentally unstable kids who might do something like that, and if a parent doesn't know if their child is mentally unstable or not, well, they're quite frankly a terrible parent and shouldn't retain custody of a house pet, let alone a child.
All of this stems from people not playing violent games and understanding what's going on. A parent looks at their child playing games for five hours each night and doesn't understand why they're doing it. They see violence in the game and when they say "Billy, stop playing that game," their kid puts up a protest. Because they're brainwashed, you ask? No, because they're having fun. If you don't want your kid to play violent games, if you honestly believe it'll turn your child into some axe-wielding homicidal terrorist maniac (and it won't, that's a fact), then don't buy the game for your kid, and actively get involved in what your kid is doing with their free time! WOW, there's a crazy idea! Parents spending time with their kids instead of relying on the government to regulate the things the kids enjoy!
Case in point: my parents played video games with me growing up. They didn't get it at first, but guess what? Over time they actually came to enjoy games. If a parent tries to get involved with what their kid is doing, then guess what? (A) you'll spend quality time with your child doing something said child enjoys, AND, you might have a bit of fun yourself! And if more parents did stuff like this with their kids, this industry wouldn't constantly get berated by the government

Prove it.
