I dont really see it that way. I think people dont like this game being called a conceptual copy of Smash Brothers when it obviously is. I dont remember a million threads for Diddy Kong Racing, Crash Team Racing, Sega Allstars, or Segas Mascot tennis games or any of those. So Im not so sure the 'loldefensiveNtards' card works here. It seems like what drove the original thread on this, and this one also is people that dont want to cede that the game draws HEAVILY from Smash.
Except people(Kamiya) aren't just saying it copies certain concepts from smash brothers, they are saying it is a shameless immoral rip-off.
