My thoughts exactly Smash_Brother. I've never followed the Smash Brothers "fan" community so I don't know how many people have said what, but I have never wanted more single-player modes to be in a Smash Brothers game. Even what SSBMelee had was too much in my eyes.
The overwhelming majority of Smash Bros fans wanted a larger single player mode for Brawl. Years before Brawl was even revealed, a larger Adventure mode was by far the most requested feature people wanted in the next Smash Bros. This is why the night the SSE was revealed, the entire internet went crazy in a positive way over the news.
To say that the Smash Bros fanbase didn't want a larger adventure mode like the SSE is complete bullsh!t. The huge majority wanted it, they cheered it when it was revealed, and they went crazy every time Sakurai revealed a new piece of info about it. Not to mention, most of them were pleased with it in the end. Yeah it didn't live up to the hype that many expected, but most people agree that it a nice mode that it quite fun when played Co-op with a friend.
Just because some of you guys despise it for whatever reason, doesn't mean everyone else did. So don't be surprised when a larger more expanded version of it appears in the next Smash Bros because this is what most of the close to 9 million people and counting that bought Brawl are going to be expecting for the sequel. Just like the majority of people who bought Melee, wanted for Brawl.
