I dunno, people are just hard to motivate into things like this.
I'm easy, like, usually if I'm given a date I'll show up unless someone dies.
It's extremely hard to motivate SA's smash scene, though - I've tried (Tibs is Vic, btw).
Then I just get snarky when people don't do what I think. Yes, I'm fair like that.
Apollo and Jamage might, but I dunno about anyone else.
In terms of "what happened" to the large scene, it was before my time but apparently Brawl killed it. But, I dunno, I've been to other states and seen healthy Melee scenes (some healthier than Brawl counterparts, like QLD) so lol, it's just lol.
Edit: Splice, I don't know. 50/50.
