I've been "importing" some past stages (including Wario Ware, Yoshi's Island Brawl, and Reset Bomb Forest) based on Mario's roll length and size as a measure. It's impossible to fully mimic in a lot of cases.



And to answer "Why", it's because a different set of stages will influence character matchup options and whatnot in the competitive sense. To answer Shaya's question, unique platform placement/movement alone is sufficient to at least consider these over the defaults. Any stage creation here that meets the standard definition of a "fair" stage is worth experimenting with. Honestly, if it leads to something more dynamic and fair than flat+plat, I'm a fan.



If you can, say, recreate the "good" parts of Kalos (the unique platform layout, for instance) without the hazards, then you can have a cycling stagelist across iterations of a tournament, or can reach some "target" number of stages without even having to consider "borderline" cases as has been discussed in numerous threads about renovating the stage selection process for more fairness.



You can functionally expand the "unquestionably legal" stagelist from Battlefield, FD, Smashville, Town, Duck Hunt, Kongo to include some borderline cases (Lylat for tilting, Siege for walkoff, Delfino for water and walkoff, Halberd for hazard, Stadium 2 for transformations, etc) redesigned without those hazards. You can extend that to other stages, too (Wuhu Island, Skyworld, Skyloft, etc), which generally have unique platform configurations to bring to the fight, but are otherwise frowned upon for their variability.



A design direction of "Make a unique platform configuration" or "make ____ without hazards" or "rebuild <Past stage>" is more than enough for me to want to try your stage out. And, unlike existing stages, if we have a problem with a custom stage, it's a matter of mere minutes to fix an issue, whereas the only option with an official stage is to start a heated debate between banning it or not.



Of course, you're also able to take platform layouts as inspiration, and expand them into new ideas. I'm working on a stage called Crateria based on Brinstar (Melee). Already imported a modification of Brinstar, but making something wider than four Mario-rolls with comparable platform design would bring new considerations to gameplay.



Will upload some of my creations whenever I find a good means of screencapping my U. Anyone have suggestions?
