I should start off by saying that SEGA Mega Drive Ultimate Collection is the same thing. I live in Australia so I have that version instead. But I played this while at the United States and it is the same thing. There is violence, but it's nothing worse than what one would see on Looney Tunes. There is 49 games in total, and some interviews with the developers of the games in the collection. The worst thing in it is Phantasy Star 2's final boss, Mother Brain, who is a god that looks naked. It's nothing bad though. There are plenty of kids games in the collection. Flicky, Sonic, Ristar, Dynamite Headdy, Ecco the Dolphin, Super Thunder Blade, Tip Top, Decap Attack, Kid Chameleon, Alex Kidd, and Space Harrier. In fact, I'd say every game in the collection is good for kids. I just recommended the best ones for them. Get this game for your kids.
