Hmmm, I guess I'll be a negative Nancy.
This probably wont do anything beyond being a cool discussion point. Sakurai likely isn't going to take many ideas from people are probably not from Smash Boards. They know online wasn't great and they'll most likely try to change it. But you'll get no where prepping a letter to change the online mode. They just wont care, and either you'll propose the same things they already thought or ask for stuff they have intention of adding.
See, that's the thing, we don't know how they felt about Brawl's online because they never really commented on it after Brawl was released. We have plenty of comments about Sakurai's thoughts during production (mainly that it was an enormous pain in the butt and he dreaded doing it since the day Iwata said that SSB3 had to have online play) but the thoughts were largely negative.
Second of all, the purpose of this project is more than just a wish list. Obviously, I haven't guarenteed anything but these were some of the other things I hope this project does:
1. Help people become more optimistic about SSB4. Right now, I believe more people are pessimistic about how it will turn out and I'm hoping that with this project that people realize that there's a good chance they will fix a lot of the mistakes they made with Brawl.
2. Connect casual and competitive players. Brawl created a pretty big divide between the two. Granted, this will probably happen again with SSB4 but I want to help people realize that, in the end, we all basically want the same thing: a Smash game that's fun.
3. Realize that Smash Bros is more than just characters. Offical details probably won't be released for another 10 months and already the discussion about SSB4 is saturated with character discussion. Obviously, there's more than a few things that make a good Smash game and I want people to realize that online will probably be a big factor in determining SSB4's overall quality as a game.
4. To connect other Smash fans on here and other sites. It's clear that Smash Bros' fanbase is very expansive and I want to take this oppurtunity to have people connect with people in other online communities about what they are expecting for SSB4.
5. Create a better picture of what fans are expecting when it comes to online play. Even if our ideas aren't used, it will still stand as a testament to what fans believe makes a good online experience that others could possibly use as reference.
With all this being said, the idea behind this project is more than just "getting our way", it's about connecting people and ideas in a community that spans the globe but is split up into different little pockets.
