Query: Good in short bursts

The katamari series is a really strange but innovative take on mini-games. It's great to play when you're bored at home and looking for pure insanity that also manages to somehow be kid-friendly. Perfect for those with short attention spans. Good game, that's why I bought it. This would be better as a portable (I haven't tried the psp one yet).
