Everything Yuna has said in this thread is completely true. I've been playing the game for the last week, and he's absolutely right: it's designed to be uncompetitive, and it's really not fun for non-casual play at all.
People keep saying that you can't figure out the game in a week or two, but they don't understand: with Brawl, you absolutely can figure out the game in two weeks. There is NO DEPTH. You don't have options. You don't have combo potential. You can't approach safely. The game is made to favor the camper. We play on 3-stock matches because 4 stocks took WAY too long. You think things are more balanced without ATs and with factory-set lag on all moves, but you're wrong: it means ANY ADVANTAGE which a character has is that much harder to get around. And do you know what follows from that? MARTH. Marth has every advantage. You thought Marth and Fox were hard to beat in Melee? Marth is now unbeatable. You simply have no chance. They nerfed his throw combos, but as those among you who haven't played the game will soon discover, he doesn't need them: he has up-B out of shield. It kills.
There's this other myth that edgeguarding is deeper now. IT ISN'T. You can't actually do it. You all think you'll jump out there and hit me as I'm returning to the edge, but you won't. Why? AIRDODGING IS COMPLETELY SAFE NOW. I'll go right through you every time. I don't have to worry about not being able to make it back. And even if you did hit me, unless I were at a very high percent, I wouldn't die from it anyway. I'd just float back to the stage, usually without even needing my up-B.
Mindgames don't exist now. You can't put on pressure. You can't vary your approaches. The lack of Melee's abilities was filled by nothing. YOU'RE NOT SUPPOSED TO BECOME GOOD AT THIS GAME. Sakurai has stated that several times.
I hated playing with items in Melee, but in Brawl, it's almost better. At least with items, you can hit people, and they'll die earlier.
I know more people will agree/understand once they've played the game for themselves, but I'm telling you now: Brawl is going nowhere. Brawl is the only fighter I've ever seen which actually took steps backward in its development on purpose. Fighting franchises don't scorn the depth which players add; they don't remove the things which give certain characters advantages; they don't try to put all players on some imaginary equal playing field. They embrace the things which work, and regulate the new depth instead of removing it, and the series gets better with time as the designers and players learn to perfect the system. Brawl is the exact opposite of that. I'd rather play Smash 64 than Brawl. And I really don't like 64.
