I got myself a PS3 for Blu-ray, and now my 9-year-old boy is contantly playing video games on the big TV. His 4-year-old sister would like to try it, but his games (sports and action games) are too complicated. I was going to get a couple of Spongebob games for her, but then I saw the reviews on Amazon, where people are saying how hard some of the games are. Too hard for their kids. Can anybody suggest a more appropriate game for a 4-year-old? If it helps, she loves Spongebob, Disney princesses, Barbie, etc. Really, though, any fun and simple game would be good.
