I paid one cent for the game (actually, I paid two cents for it, as the site crashed on me during the first transaction and I was forced to do it all over again). I don't feel bad about it, though. Fact is, for me this game wasn't worth buying. I tried the demo and it was pretty enjoyable, but not enjoyable enough that I felt like spending money on it. However, if offered the chance to get the game for free, or in this case almost free, then sure, I'll take it. How exactly am I a pirate? 2D Boy told me to pay what I felt like paying and that's what I did.
Your argument is just as bad as claiming that a pirated copy of a game, song, movie etc. automatically equals a lost sale.
So more insanely difficult piano pieces to learn.
Insanely difficult? I take it you're not familiar with Scarbo, Islamey, Gnomenreigen, La Campanella as someone else mentioned, etc.
From the game's Wikipedia page:
Nintendo enlisted outside help from various developer studios, including Game Arts, who spent excessive amounts of time playing Super Smash Bros. Melee.
Calling Game Arts "the developer for Super Smash Bros. Brawl" is pretty disingenuous. But it certainly is a good way to make people think that your game probably won't suck, attaching the Smash Bros. name to it like that.
I stopped reading as soon as your silly bias against the Wii reared its head. I probably don't even really disagree with your list, but it's hard to take you seriously when the fanboyism is so blatantly obvious.
