@1080sage@YoshiCookie DOAX3 Scarlet adds 2 characters and I believe a few more songs, it's basically a "Definitive Edition" of sorts, that said the 2 additional characters ( Leifang and Misaki ) can be bought on DOAX3 Fortune.
@1080sage@YoshiCookie Only the Scarlet version is censored in regards to items that improve "physics", the original game is not censored which is the one I bought.
