And I'm saying that it caused a lot of trouble for an end result that wasn't satisfactory. Brawl's development was already riddled with crap and bad decisions, throwing Sonic in at the last second only caused more problems, to the point that a completely original and popular character was canned. Don't call me biased because I want the best out of a Smash game. This has nothing to do with Sonic, and everything to do with what happened the last time we got a last-minute character. It's not a situation I want to be repeated.
As Jonesy (sorry, just finished reading Dreamcatcher) pointed out, this is Rayman, not Sonic. Rayman was practically a non-entity before his recent, more popular titles.
I'd like to see a source proving that Sonic threw a wrench in the works of Brawl's character roster, because I've never seen anything saying Sonic was the result of other characters being cut. All I've heard is that he was a last minute addition, which led me to believe the roster was final before Sonic's inclusion, but they then added him in due to his demand and relevance to Nintendo. Unless you can prove that Sonic did force other characters out of the game (which I HIGHLY doubt - how the heck could a character like Sonic prevent MULTIPLE characters from being forced out, including a veteran like Mewtwo, who likely could be implemented easily? If modders could do it, Sakurai and his team could have done it like it was nothing), I'm viewing this comment as biased. I won't argue with your opinion of the character's portrayal, as that's your opinion, and my username should be enough to tell you what I think of Sonic's portrayal in Brawl anyway.
Also, your "Rayman was a non-entity" claim is just objectively wrong, as I already proved. I will repeat, the Starfox franchise has a global sales number of about 11 million TODAY. The Rayman franchise had 10.5 million global sales AS OF DECEMBER 7TH, 2001. That is far from a non-entity, especially since Rayman 1 and 2 were the only Rayman games in existence at that time (as well as different versions of the games, and an educational spin off or two). You still have Rayman 3, Arena, M, Raving Rabbids, Origins, Legends, handheld spin-offs, digtial copies of afforementioned games, and mobile games to take into account, as well as later ports of his older games, to reach today's global sales (which VGChartz has a very inaccurate number for right now, as it doesn't account for the digital sales, and doesn't even have numbers for some games). Rayman is literally the game that put Ubisoft on the map. Without Rayman, franchises like Prince of Persia and Assassin's Creed would never have come to be, as Rayman raked in the money for Ubisoft.
I was literally only posting the Rayman news in case anyone was interested in a petition, and I don't see it doing any harm.
