First off, I'm not a troll.
I've only played in 1 tournament for SSBM, but I've always adhered to tournament rules. I was never that big a fan of items, because they'd either be pathetically weak, or severely overpowered and unbalanced, compared to a similar game like Power Stone where most items are fairly balanced. I did like a few items though, like the Warp Star because it felt cool, and the Star Rod is pretty fun, and a few other fun items like Flippers, Bumpers, and sometimes the Barrel Cannon.
When I found out about certain levels being banned, that's when I felt like the game was being stripped down a bit. I didn't care that much about some of them, but levels like Big Blue and Mushroom Kingdom 1 were some of my favorites.
Regardless, I stuck to the tournament rules because my very favorite level, Poke Floats, and another level I really like, Rainbow Cruise, are legal. I just really like wacky levels, it takes some skill to adapt to them, and breaks up the monotony. I do like Final Destination for really intense matches, though; it's so dramatic how it's just you and your opponent, nothing more, nothing less, and the background is cool looking. Battlefield kinda bores me, but that's neither here nor there.
Seeing the updates for Brawl, however, I find that almost all of the new items look fun and most of 'em not too overpowered, and really hope the Warioware and Pictochat stages do not get banned, but it seems like New Pork City will get banned for sure; it's as big as the temple AND can one-hit ko people as part of a level feature, and Norfair will likely get banned, even though it seems to add a fun "King of the Hill" style of gameplay, and it seems like it could go either way with The Summit. Heck, even Skyworld might get the axe, and so help me God, I will be done with tournament rules forever if Shadow Moses gets banned.
What feels close to crossing the line for me is that a CHARACTER might be unplayable in tournaments. That might be the last straw for me. I agreed with items being removed because of the exploding containers, I begrudgingly agreed with levels being banned, I have no complaints with Wavedashing and other advanced techniques, but a character?
It feels like the fine line between making a game balanced and gutting everything is about to be crossed. I mean, hell, it's bad enough that a character might not even be usable, but Final Smashes will likely be unusable too, and I was excited that Brawl would have them, before I realized the Final Smash thingies would be items.
Heck, I'm beginning to see why they compare the tournament rules to removing Weapons from Halo 3; perhaps some items or levels might be unfair in some circumstances, but is it really worth stripping out the soul of a game to make things "fair"? I mean, couldn't we have just let some stages be choose able if neither player was using a character that could take advantage of a level's design, ie. Bowser vs. Bowser on Hyrule Temple?
Seriously, sometimes it feels like the people who decide the rules are like parents that want the best for their kids, but are a little too overprotective and a little too strict.
