Based on the very few space themed mario forever worlds I’ve seen gameplay of, we can really have some more creative space themed worlds like World S which is one of the best I’ve seen as of right now. My idea is pretty wow, so wow that i get excited thinking about it. Ok so its space themed right? I say there is a time where bowser goes to nasa and steals their rocket ships and it sends bowser to the sun because of the lava theme n stuff on his castle levels most of the time. Huh? Ok enough with the plot so since its space themed there should be alien enemies. Maybe have references from the mario and luigi partners in time with the werid alien shroom thing. Also add a unique warpping system like using black holes instead of pipes and maybe add a secret time distorted level only accessible with a secret black hole or something. As for the power ups add a cool pineapple that makes mario run really fast and lets him ignore gravity. When that powerup is used he can jump like he’s on the moon. Oh and luigi should be a mini boss in this world, i always wanted to hurt luigi not while playing as him tho. At the end when you beat bowser at his sun planet castle thing it should end by it starting to explode and right after you beat him you go to the final level and have a countdown before the sun explodes and you have to get on nasas car drone ship. Then a cutscene of mario escaping and trying to go to earth but a meteor hits his nasa drone ship and he lands on a weird planet that looks very tropical and that’s where the squeal begins. I want a cool space themed world with a great plot even though there really is no plot in mario forever games most of the time l o l.
