I was referring to Roy prior to Melee. And your point wasn't that Chrom wouldn't be added for advertising, but rather that Roy was and it's thus okay to do the same with Chrom. Both points of which are false.
You shouldn't say one thing and then say your point was something completely different.
I hope to god you didn't just make a reference to a new spongebob episode, let alone expected us to get it. (also love the new icon)
It wouldn't suprise me. Sakurai saw the Brawl roster as perfectly feasible (I agree to, as it had everyone necessary with the exception of Mewtwo, Mega Man, and Bomberman.) It would make sense for him to add what he originally planned to have in the last one. Not saying this will get Roy in.
Well I am not so sure, Ridley seems like he has always been a pretty necessary character. Not to mention Villager as well (even though at the time Sakurai didn't want him in the game, it doesn't alter the notion that he was a necessary). Meowth, perhaps? He still has a prevalent role as the primary antagonist of Pokemon (anime of course, which is where Sora Ltd. draws inspiration from). Not to mention the roster had a lot of unnecessary characters too. Lucas and Game and Watch really jump out to me. I think the roster needs cleaning up personally.
Some honorable mentions missing are Waluigi (controversial, but he is a symbol of party games and the final brother), Tingle, Waddle Dee, Samurai Goroh, and K. Rool. Obviously once we apply hindsight we are also missing Toad, Bowser Jr., Palutena, and Little Mac.
My main point being, feasible is subjective. There are still a lot of necessary Nintendo icons missing or characters overlooked by Sakurai that are already in the game (Such as Waluigi, Tingle, or Goroh). No doubt Brawl's roster was fantastic, but it wasn't perfect. Obviously we cant fit in Bowser Jr., Waluigi, and Toad despite their importance to Mario. Same with Tingle. Goroh and Porky are from dead series. So the omissions are understandable and expected. It doesn't mean that the roster is everything that it COULD be.
