I know I'm fantasizing here, but I really really hope to keep the kids away from the videogame world as long as possible.
Maybe it was Dave Barry who said that he never wanted his kids to watch videos; he pictured them doing good Amish things like weaving and churning butter. Then he gave in, and eventually his family bought the entire Disney collection. Well, my kids watch too many videos already, so my Maginot Line (for now) is videogames. They're not yet 5, but hear their friends talk about 'em, so their interest is piqued.
I guess I think of videogames the same way my parents thought of TV---new opiate of the people. My folks succumbed to their first TV set when I was 14 (after my siblings and I were already into books). I'm probably obsessing like my parents did.
Shit, child-rearing is scary. Wish we were back in the pre-AIDS, pre-crack, pre-internet, pre-Columbine good old days.
