One of the most anticipated features of Super Smash Bros. Brawl was the inclusion of third-party characters in a series that was previously made up entirely of Nintendo’s first-party characters. Unfortunately, many people (myself included) were disappointed when they learned that Sonic and Snake would be the only playable third party characters after originally hearing that the developers planned to include more than two.
Once again, with new Smash Bros. games on the horizon, I am hoping that additional third party characters are added, and there is one long running series with a huge collection of characters to choose from: Final Fantasy.
