the only thing here that i would consider a mainline super mario game is yoshi's island
donkey kong and mario bros predate the super mario series
rpgs and level makers are very different experiences from normal platformers so i would call them spin offs
remakes and dlc i wouldn't consider worth...
was not expecting to get hit like this
unfortunately due to the not being out until all your fandoms are named rule i'm still invincible as i am a fan of 1000 animes
i think usernames are still considered "taken" even after you've switched off of them, so someone having been "lady" in the past is probably what's preventing you from switching to it
