I'd really want anything from MOTHER 3, but if I made it, it would be Tazmily village/town (It would change on startup like Mushroomy Kingdom in Brawl) it would be a "scenic" stage, like Delfino Plaza and Skyloft. In Tazmily town, it would land in the main plaza, at the beach, at the police station, at the train station, at the retirement home, at the farm, and at Lucas's house. Tazmily village would land in the same places, but the scenery and platforms would be different (except for Lucas's house since it's the only place that stays the same.)
Music:
-
Tazmily Village (Would probably be updated, but this is the original.)
-
Eight Melodies (Was cut from Brawl, so this would be perfect for its return.)
-Other music from Brawl, like
Snowman and
You Call this a Utopia?! (I just like Snowman, and YCtaU?! matches Tazmily town after being overrun by the Pigmen.)
