I'll admit Brawl is somewhat of a fanservice game, but that's not where most of its depth and appreciation comes from. In the end it wouldn't have mattered because the game still works on unlockables(music, trophies, stages, characters, even modes). A lot of games can get away with this, but Brawl must be a party game so it can't right?
It's fine he brought it up though. Actually good of him to do so since it is silly in my opinion. However it doesn't really justify/contribute to his conclusion on the game.
I would put it at the same level of saying "FF7 doesn't have the same music as it does in the commercial it ran"(which it doesn't, fuck!). Seems a little odd to even bring it up now.
