Mantis, you are listing the same argument that every other 08er has thrown at us before. What you misunderstand is a lot of Anti-Brawl people wanted Brawl to be good and it didn't meet our standards. Yes I was expecting a different game than Melee, and from the E4 All Demo back in October(/november? I dont remember) we knew that many things from Melee were gone. I gave it a chance regardless, but after 5 months straight I was bored, while after 4+ years of Melee I still feel like there are things worth pursing and learning.
The fact is the game mechanics in Brawl (floatiness, lack of hit stun, lack of combos, etc etc) don't make it worth pursuing in my opinion. You are also misinformed in that I doubt many people were crying about the transition from 64 -> Melee. A competitive smash scene didn't exist, and it started and evolved through Melee. People are more upset now because the Brawl physics engine has limited what was possible in 64 and Melee, and you say "things change get used to it!" but who says I have to?
I have no problem with change, but we have a fantastic established fighting game that people gave up on for a downgraded, flashier looking, campfest of a sequel. We didn't want "the exact same game with more characters, and speed etc", but what we did want was a tolerable game that didn't promote camping and EVOLVED upon Melee, not make it simpler and more shallow (unless that's your idea of evolution). Seriously, go compare Brawl to the other fighting games at MLG and EVO, it looks like a freaking joke.
I'm really trying not to be bitter, but people are entitled to there own opinions and if you like Brawl so much stay out of the Melee boards. If you are willing to invest time and actually try to get good at this game than you are welcome, and I GUARANTEE you will appreciate it more than Brawl.
