Not neccesarily the character, i could care less. I just cannot understand why anyone wants to play a bunch of minigames more boring and with less graphical fidelity as a simple game of solitair on any pc.
While i haven't played any RH game yet, it's a title i would eventually like to check. always liked the G&W galleries series since their first game on the GB, and the wario ware series. the concept is simple, yet fun, some mindless casual fun sometimes is just nice. plus the music is pretty catchy. and unlike other musical games, it centers all about the rythm. probably people who have played the saga could elaborate more.
Why on smash? well, Rythm is way more important that most people realize in fighting games. Flow, momentum, prediction, if your opponent manages to predicts your rythms you are doomed. on the other hand, while one have a fixed amount of tools, for say aproaching. mixing them in unpredictable rythms is what canmake you get the upper hand. thats why a rythm based moveset have so much potential for being awesome. I'm pretty sure that Sakurai also realizes this, and sees moveset potential in Rythm heaven characters. the thing is how well it will come on execution.
Annnd, while not massive, RH have some meme potential. (which makes it known around certain fanbases)
Aaannnd now.. think of how I can relate this to ridley...
Someone really needs to do a RH video with Fusion Ridley scream... (sorry for the offtopic
)
