Geez, the game is kinda out sort of so we can talk about it to a degree, but most of us haven't played it yet so we can't say a whole lot.
But, it is a new game, im sure something will develop that will be awsome as far as depth; i believe like Samurai Panda said that Brawl is "The evolution of smash" and so i think any pros from melee should be able to convert very easily, albeit with a little adjustment but true smashers at heart should be able to switch over fairly easily.
so lets please Evolve as a community, We need some sort of official "Brawl will replace melee as the tournament game" kind of petiton or something, the community is what makes the game, not whatever physics exploits were/were not included in following games. Let's please not kill Brawl it looks like an amazing game that is the next step up im smash play, even if its not exactly like its predecessor, it still looks incredibly deep. Some say not to look at it like melee, and that is true, but its missleading. We need to look at is as smash; regardless of what comes after that in its name, they are somewhat comparable, and yet different at the same time.
Let's just decide to play brawl and MAKE it competative; we'll find something, in someways we already have, the bowser infinate jump thing is awsome :-)
