I'll assume and suppose a few of them are also, well, getting older. They want a return to a simpler time when they could be bouncing off the walls at the thought of a new Smash Bros., as I did when I first saw Super Smash Bros. Brawl's trailer. Goddamn it was such an amazing time. I remember rewatching that trailer so many times , having lived with Melee and Smash 64 for the majority of elementary school, seeing my favorite Melee characters transform into newer and shinier versions (except for Kirby, who's just confused), and just felt I could burn and burn forever about it and what kind of game we'll exactly be getting.
People want to relive this I'm guessing. I kinda do myself! I think we all had our "hype explosion" moments during childhood. But I think I'm past this, at least for official announcements. Don't get me wrong, I kinda had the same feeling when Odyssey was up and when Smash Ultimate was announced, but it's nowhere near what Brawl and Super Mario Galaxy have done. It's a lot more subdued.
Anyhow, I might be smarter because hype's a very dangerous thing. Brawl sorely disappointed me in the end before the modding scene arrived. Brawl was great on arrival, but just ended up getting more and more sour for me over time. Also, you know more and more about how rotten, exploitative, and greedy the game industry is, so it puts a damper on your expectations. I find it a good thing I don't get as super hyped as I used to given I know about Nintendo better. They exploit kids.
