Do you have any more feedback regarding this?
Well I'll try to remember some stuff we discussed already.
1) It was generally agreed that if we made a custom stage, it would be a new starter which would act as a replacement of either Lylat Cruise (if it's a starter in your region), Yoshi's Island or Pokémon Stadium 1 in a 5 starters ruleset. The reason being : there is no need for a new CP, but there is a need for a starter since starters are usually considered as counterpicks against MK. It would make the dude less 'over the top' and stop most of the banning tendencies we have always had in France xD
2) Hacking issues are not such a problem in France, so we had no reason not to use the
Stage Studio which basically gives us more possibilities in designing a stage (we can make PS1-like pillars if we don't want MK to scrooge, we can make blocs overlay which allows for kool stuff, have a 252 blocks limit instead of 50, and choose the spawns, in example...). Stages made that way, even if they are not 'valid', are not considered to be hacking by the wii. They work on any unhacked wii. We decided to keep it minimal though, because we want our scene to be as globally appealing as possible and since hacking is indeed a taboo in other countries, we didn't want to alienate ourselves.
3) We chose to be really careful with our stages. Every block had to have a purpose. It goes from obvious stuff like 'no walkoffs, no walls, no cave of life' to 'the background can change olimar's pikmin distribution and it can make or break him in some matchups', and 'is the stage itself where I want it to be : low enough so spikes still kill snake, high enough so DDD isn't broken, near the side boundaries just the right amount', ...
4) There are a couple glitches we have to be aware of with the stage builder and the stage studio. Here are those I kept a screenshot of :
You can go through the solid block if this configuration is used. Considering that MK's halberd exploit is banned, I'm pretty sure this would make the stage instant-ban.
With the stage studio, you can do this. And it makes it so that side of the stage has got two ledges. If you try to do any getup movement out of the lower one, you will be pushed back offstage instantly.
If you intend to do a PS1-like pillar, use ice blocks because else each block that is out of the boundaries will have a ledge.
If you overlay those two blocks, the square block will only have a ledge on its left. I couldn't get the mirror version of this to work : if you turn it around the block will have both its ledges.
No photos for this :
-If you try to overlay some platforms to get a custom-sized one, you may have collision glitches which will stop rolls, dashes, and dash attacks.
-If you want to place an horizontally moving platform in the floor, the same glitches may occur.
Both these situation are really hard to predict and stop the flow of the match greatly. I do not advise to use them.
5) We have tested a handful of stages already.
-One of them was a flat stage with two blocks high in the air which would be a micro cave of life that wouldn't 'randomly' get you saved. You would have to conquer a small zone in the middle where if hit horizontally you would be able to DI towards one of them and attempt to tech. All of this would take actual skill and that was the idea behind it. The full blocks provided additional, harder to reach ledges which would encourage poor recoveries and upBs from the floor. We discarded it because it provided ledges facing the inside of the stage which would make the air camping risk/reward ratio be really low.
And was called 'Smiley' because of how the blocks mimicked eyes and the stage mimicked a mouth. Kinda like :| but turned 90° clockwise.
-Another one was a flat stage with platforms above both of its ledges which would allow for different recovery routes and edgeguarding waypoints. It wasn't that bad, it's like whenever you were offstage, the smashville platform teleported above your ledge. Besides that, the stage didn't bring anything that FD didn't do better so we figured out it would be wise to look for something else. Iirc, it was called 'Smashvillage'.
-Yet another one, which required the stage studio to be used, was a flat stage with two medium moving platform rising out of the floor alternatively on both sides of the stage (with a 1 block offset from both ledges so the rising platform wouldn't make the ledge 'disapear' when they overlay with it). It was quite cool besides the fact that it would stop some CGs (which isn't such a disadvantage). We added a pillar to prevent scrooging just in case. It was called 'Mr.T' due to the T shape of the stage and the Mr.R-like stuff you could perform on it.
I'll add stuff if I remember anything else, but that's it for now.
