Cowboy Bebop at His Computer: Shortly before the release of v0.9b, a number of news articles started giving out some hilariously inaccurate details. Polygon spelled McLeodGaming as "Macleod Games", and one Spanish-language news article claimed that the game was a one-man project, and another claimed that not only was it "back" after eight yearsnote While that is how long it's been in development, the article seemed to imply it was on hiatus that entire time. but that Shadow and Ryu were playablenote Clearly getting confused with Super Smash Bros. Crusade, where they both actually are playable.
Doing It for the Art: Super Smash Flash and early versions of 2 were just a hobby for some college buddies, but soon, 2 became determined to become a full, quality video game. The devs work on it close to nonstop, leaving very little free time for themselves, and... oh yeah, since it's a Fan Work, they're legally forbidden to make any profit on it. They're doing all this for free just because they wanted to make their own full-fledged take on Super Smash Bros.
In an interview during Apex 2014, Cleod explained that he has always been interested in pushing a given medium to its absolute limits, starting from when he made games for the TI-83 calculator in the early 2000s. This is why he enjoys working in Adobe Flash even with such an ambitious project - simply because everyone sees it as a horde of crap that's apparently incapable of anything serious.
Schedule Slip: The reason the team no longer sets any release dates, not that it stops the Fan Dumb from asking.
"We're a team made up entirely of freelance non-profit non-professional developers who can only spend so much time on this project. This project is but another responsibility next to our other stuff such as education, work, families, superhero alter-ego's etc. etc. We can't spend as much time on this game as we'd like to, and we work with a relatively small team, meaning that even a single member being unable to work due to other stuff has a huge impact. This all makes it very difficult to set exact release dates, and we don't want to post a date out of the blue only to disappoint later."
—Steven, Super Smash Flash 2 developer
Throw It In: Blade, the first character coded into 1, was originally intended to be Dummied Out as just a test character. But, he ended up in the final product along with his counterpart, Blue.
"Take note that the wiki is not ran and/or endorsed by the Mcleodgaming SSF2 Developement Team. This may mean that information appearing on the wiki may be based on speculation. One can find an enormous amount of 'beta stages' or 'beta character designs' from early days that we as the SSF2 developement team do not consider 'beta' (since it was never in the game at any point). This also goes for statements appearing on the wiki; if it can't be traced back to a post on one of our official media (or the FAQ topic) then don't consider it true.
"That being said, we are very grateful that we have a fanbase that is dedicated enough to set up and run a wiki for our game. We really are! Just be aware that statements and information appearing on the wiki may not represent our product."
The old roster in its entirety, and most of their sprites, can be viewed here.
Among other things, removed stages include the two Test Stagesnote White with a green floor, simple and MS-Painted. Stage 1 was perfectly flat and Stage 2 had a curvy terrain., Brawl's Battlefieldnote Replaced in v0.9b with an original design, Brawl's Wi-Fi Waiting Roomnote Deemed redundant due to having an identical layout to both Final Destination and Hazard Switch 3DS, the Temple of Timenote Deemed redundant due to Chaos Shrine having a near-identical layout; replaced by Clock Town: The Final Day, and Mushroom Kingdom IInote From Melee; replaced by the original design of Mushroom Kingdom 3.
Characters used to have individual revival platforms to appear on whenever they lost a life. It was later deemed to have looked good on paper but not in practice, and replaced by a universal one like in the official Smash games.
The old Dojos are a gold mine of old information, a lot of which looks just plain ridiculous now:
Wario was planned for the first game, but ended up being scrapped. He was one of the new characters in the second game, following his appearance in Super Smash Bros. Brawl. There are remnants of his planned appearance, like the Floating Islands Stage, which had sprites and enemies from the Wario Land games.
