Alright, alright. I'm convinced haha GHZ will remain in place of FoD. I'm still not super sold on GHZ, but the arguments against FoD are many and justified, and no way in hell will I accept Wario Land as a starter, so GHZ will simply have to do.
So, I'm gonna go off on a hypothetical balance tangent here, cause what else is there to discuss in this thread atm? No TL;DR, just read it or don't. Now, I'm gonna skip the discussion on starters and just focus on the balance of stages overall. I will, of course, start with the obvious 3.
BF: Medium width, Medium ceiling, cramped layout
SV: Medium width, Medium ceiling, open layout
PS2: Large width, Low ceiling, open layout
BF and SV balance each other out by having similar dimensions and one being cramped and the other being open. Now because PS2 is a large stage with a low ceiling and an open layout, we would need a small stage with a high ceiling and a cramped layout to balance it out.
PS2: Large width, Low ceiling, open layout
FoD: Small width, High ceiling, cramped layout
Hey, that's perfect! Wait, there's only 4 stages. Well, clearly we need more stages. But bear with me, I'm only going slow to detail the balance side of things. FD is a pretty iconic counterpick, so let's add that on to the list
FD: Large width, Low ceiling, open layout
Okay, so FD is very similar to PS2. Unfortunately, there are no more FoD's to balance FD out. So we'll have to balance out as many of these attributes as possible and then add other stages to balance the rest. FD is as wide and open as it gets, so what's on the other side of that extreme?
FD: Large width, Low ceiling, open layout
WL: Small width, Low ceiling, cramped layout
So as far as stage sizes and layouts are concerned, we still have balance. But now we have 2 extra low ceilings. To maintain balance, we need 2 more stages, both with high ceilings. If they could both be medium sized stages, that'd be ideal, but oh wait, no they can't, because we barely have any medium stages, none of which have medium ceilings. So it has to be one small stage and one large stage. Well, that makes things easy.
GHZ: Small width, High ceiling, medium layout
DS: Large width, High ceiling, medium layout
I say medium because of the stage sizes. GHZ is open relative to its size, but because it is a small stage, it is still more cramped than SV/PS/FD. Same with DS, it is cramped relative to its, but because it is a large stage, it is more open than BF/FoD/WL. Regardless, the 2 stages balance each other out and balance out the low ceilings. So here's the full list so far, in order from most cramped to most open:
Wario Land (Small, Low, cramped)
Fountain of Dreams (Small, High, cramped)
Battlefield (Medium, Medium, cramped)
Green Hill Zone (Small, High, medium)
Delfino's Secret (Large, High, medium)
Smashville (Medium, Medium, open)
Pokemon Stadium 2 (Large, Low, open)
Final Destination (Large, Low, open)
Now, if it were that simple, this list would be just about perfect. Everything is evenly distributed 3/2/3. But it's not that simple. Here are the problems:
1. Delfino's Secret is a little inconsistent. Most of the time, it fits the description of "cramped for a large stage", but occasionally, due to the moving platforms, there are some layouts that are more akin to being called wide open.
2. The actual problems. We need 5 starters. We only have 2 medium stages. This means we either have to A. Have 2 large and 1 small stages in the starters, B. Have 1 large and 2 small, or C. Only have one of the medium stages. This will never happen and shouldn't happen because Battlefield and Smashville are the most balanced stages in the game.
We can't really solve that first problem, cause Delfino is as good as it gets for a "large, but kinda cramped-ish" stage. Can we solve that second problem? What would we need?
???: Medium stage, medium ceiling, medium layout.
A third medium stage. A true medium. With this stage, all dimensions would be distrbuted 3/3/3, and we could 1 small, 3 medium, and 1 large stage in the starters.
But we don't have this hypothetical stage, so I just wasted everyone's time :/
