princess on ice came out first in america then japan made it more anime-ish which IMO looks way better. hell, just look at the japanese cover and compare that with the american version. which is better? you guessed it, japanese.
anyways, happy star band and making the music are not the same game. as someone said before, happy star band is getting localized as rockin' pretty.
i have played happy star band and its quite good. 4 styles to play from (guitar, bass, drums, electronic piano). i cant wait to play it in english. ill buy all the outfits. as for princess on ice japanese version, i havent played it yet but i will when i get the chance.
