Whether it be fighters, stages, spirits, music, Mii costumes, or anything else, this is intended to be a list of all games from all series in Super Smash Bros Ultimate. This list is is completed as far as my research goes, but any additions would be greatly appreciated. And of course, if they somehow decide to do more with this game, I'll update the list with it.

For my sake, this will not be counting mobile games, LCD games, Flash or other browser games, edutainment games (unless the entire series is edutainment), crossover games without the series name in the title, or any other exceptions I might decide on. Remasters/ports/remakes/deluxe editions/etc. will not be counted separately. If two versions of a game are entirely different, they will only have one counted (i.e. Metal Gear Solid which was on PlayStation and Game Boy Color).

Finally, this will not account for any game released after the final content had been added to Super Smash Bros Ultimate (which was the Evil Ryu Spirit). So this will not be a continuing list.

If you can see this list, feel free to comment games I might have missed.

(Ignore the strange order of the list)
