So I have played quite a few rhythm games this weekend, went to the biggest video games convention in France which conveniently takes place in my city
Here's what I played and what I thought about them.
beatmania IIDX: HAPPY SKY, DistorteD, DJ TROOPERS, EMPRESS which were awesome but also insanely hard, couldn't clear anything above 4/12 in terms of difficulty
pop'n music: Iroha, Carnival, Fever, Sengoku Retsuden. I already knew the games and played them a few times so I knew what to expect. Still really fun though.
Project Diva 2, which is surprisingly fun despite me not being the biggest Mikutard ever. It had my favorite Vocaloid song as well, From Y to Y, which was awesome. Sushi liked Hatsune Miku no Gekishou a lot.
osu! on a touchscreen. Too bad it wasn't really suited for the game, so it didn't register short taps rendering streams impossible. Some maps were still really fun to play though, especially MoonFragrance's. We also had the opportunity to play with Sushi's mouse and tablet but I couldn't play anything correctly with them so that was out of the question.
