Good, interactive games with lots of multi-player offerings and ideally suited for more casual/younger gamers.

Playstation and XBox also have a great selection of games, though they tend to be geared more towards hardcore gamers. In my opinion, because of the push for awesome graphics displays, the games seem designed more to reflect "real world"-type situations, hence the likelihood that they are more mature in content.

Just my take. I'm sure many will disagree.
