Now, I don't want any misunderstanding so everyone should read this post exactly as it is, written by one of those Nintendo fanboys who has nothing better to do but play Brawl by himself. So take from this post what you may.
My first concern is that it seemed like Yahtzee didn't even play through the whole game, or even most of it, or even any more than the two or so hours it took for him to come up with enough stuff for him to talk about really really fast for four minutes.
Second, if you don't like fighting games because of button mashing, than anyone who's played Brawl for any decent amount of time (see point above) would know that Brawl actually does a better job at this than most fighting games. In your normal fighting games you have the options of horizontal attach, vertical attack, kick, and block. Which, when you button mash together usually results in your character at least doing something. With Brawl you've got normal attack, special attack, and jump buttons; usually resulting in anyone who's trying to button mash to just jump around and perform incredibly weak attacks and sometimes even kill themselves (i.e. Yoshi egg roll themselves right off the damn stage). All this means that Brawl rewards you for actually learning the basic controls because it means you spend a lot more time actually fighting and a lot less time jumping around like a dick.
Third, if you spend any amount of time playing the game with a basic understanding of the controls/moveset (see the last TWO points above) you know that YOU CAN see what other players are doing (NOT just a brightly colored maelstrom, LSD induced, clusterfuck) and to be any good you DO have to respond to other players moves. I think the fact that there are players who are good at the game, logically seems to follow that they can see what their opponents are doing and counteract them.
And yes, it IS annoying that all the characters that have been getting so much hype are locked until you practically beat the game anyway. But if anyone is actually surprised by this fact... Well, there's just no nice way of putting this, you're an f*ing moron. Game developers have been doing this for years, and now it just seems like your trying to hard nitpick and find flaws.
I suppose what really irks me however, is that there are TONS of reason to not be absolutely in love with with Brawl, or even like Brawl, but Yahtzee seems to only comment on these in passing. The single player was so repetitive and the tacked on now-do-it-all-again-so-we-can-make-the-game-twice-as-long element was so horrible that if anything should be the down fall of Brawl it should be that. Not to mention the poorly supported Wi-Fi play..
So stop complaining and just start bashing Pikachu's skull in with a frying pan.
