Oh yeah. They're 6 and 7. A lot of people DIE in FF13. I'm not sure a little kid needs to see that kind of stuff until they are at least 7 1/2 years old.
I'm not even sure it the PS3 is the right gift for a 6 or 7 year old, either. In all honesty, I don't even think that a Wii is a good gift for them. Get them some DS games or if you really want to do them some good, buy them some sort of ball or bicycle or even a trampoline. Don't set them down the path to the dark side so early in their lives!
