Yeah,
I'll admit during this I checked out SG too, read some forums and watched some videos. But for no reason other than 'this game has a very dedicated community just like smash, lets see what their actual game is like.' And I wasnt overly interested.
The fact that I've never even heard of an SG side event at any smash tournament ever, is what makes me think people arent being genuine in that they will legitimately try it out now. A community raising money is completely independant of whether people will enjoy their game. No different to if say, halo was involved in this tbqh. If the fact that another game community raised money is enough to make people want to play that game competitively, then so be it.
I can just very easily imagine that if ANY OTHER game (ones with these small tight-knit communities) came 2nd, wed see the same reaction here, as an appearance of humility.
I dont see how SG differs from any of those other fighting games vying for a spot, in terms of how it would be received by the smash community if suddenly thrust into our attention.
