Seriously though, rhythm games are great. I managed to pretty much 100% the DS version of RH; I'm up to like 41/50 medals on the Wii version since I got it a few weeks ago, but some of them get real tricky. Fuck Love Rap and Remix 10 holy shit.
EBA was also really damn good once you got to the hardest difficulty, but after playing Ouendan I'd say it might be a little better. I still need to try out Ouendan 2.
I'm curious to see what the Miku rhythm game(s) on PS3 are like, I don't remember if the first one came to Europe, but the second one I think is out later this year. I'm interested to see how it is.
Besides that the only other sort of rhythm game I can think of right now is that weird new f2p music/rhythm based FPS, Chroma, coming out whenever (soon according to steam). It's being developed by the former Rock Band devs Harmonix so it might not be completely shit.
Rhythm Heaven Wii U/3DS fucking when though
