George stopped...

I can't I have to be the one to do this because I'm the FFIX fanboy around here, formerly having a schizophrenic gimmick that feature both Zidane and Garnet/Dagger, but I digress and here we go. A commercial for Coca-Cola doesn't instantly make FFIX better than any game. Look into the game to find how superior it is to other FFs. For example, the characters were all put well into the story, the setting is more like what veteran Final Fantasy players expect from an FF, it houses the most realistic romantic subplot in the PS1 era and possibly the entire series. But certainly not due to a Coca-Cola commercial, it doesn't make me want to play FFIX, it makes me want to drink coke.
