I liked the Brawl era speculation. The DOJO was by far the best pre-release hype builder, with new updates every day and the possibility of just having a newcomer dropped on you. And people were more flippant back then, but they also didn't get all ****ing Pepe Silvia to nearly the same extent they do these days. It was meaner, but at the same time, chiller.
Plus, there was no leaker culture. Leaks, or at least leaks people paid attention to, were few and far between, and there was no **** riding on people pretending to be insiders. Also, people sort of treated things like normal fighting games, where they didn't get all precious about the possibility of cuts and act like you were wishing death upon someone if you suggested a certain character might not make it back.
And yeah, the way people spoke about characters or topics wouldn't fly these days, and before the DOJO started updating regularly the droughts were insane, but there was a lot that I preferred about the general disposition towards speculation then. On top of that, I think we got the best selection of newcomers, and the biggest two megatons to date, being Snake and Sonic.
And having said that, I know it's 2020, and I know Dedede's FS is better now, but I still hold a special place in my heart for the Big Gay Dance.
