I don't actually have any of those Guitar Hero/Rock Band games. I have sometimes considered getting 3 on Wii, since I occasionally play that with some of my friends and like some of the songs, but I've never actually done so.
As for rhythm games in general, I used to play DDR too, but Reggy and I don't get to play that too much anymore. I've also recently purchased Patapon for my PSP. I haven't played too much of that yet, but it's pretty fun. The idea of commanding troops by executing different combinations of sounds is rather amusing. XD
