In all honesty though, the vid title was sarcasm. Perhaps it wasn't clear enough, oh well. DDR/ITG/SM/FFR are the notable rhythm games that use upscroll. IIDX/Pop'n/O2Jam/newly implemented Osu!mania mode are the notable rhythm games that use downscroll. Not every rhythm game but the games noted (first set) uses downscroll, such as Technika and Osu (standard/Taiko, Catch The Beat isn't really a rhythm if you ask me..). Please don't make stupid comments like that again.
