What? Dude you are making no sense. Modifying something is not the same as replacing it. PM didn't go "hey look, the new Brawl!". It is a Modification not a Replacement. It didn't go onto store shelves, and it didn't have the purpose of stealing Brawl's crowd. Also, you said it yourself, that Brawl is a casual game. If PM was trying to replace Brawl and release a better version of Brawl, they wouldve released a game that is better than Brawl for casuals, but they didn't. Since Brawl was made for a casual audience, PM modified it and released a modified version of the game online to give to the competitive players. you see it? look closely.
BRAWL = CASUAL and PM = COMPETITIVE
notice it now? there is no way Brawl players got stolen, unless you're talking about tournament players, but then you're just contradicting yourself again because Brawl was meant to be played casually. I don't understand how you think you're right. People have opinions, but your sis plain idiotic with you countering your arguments.
