I'm a bit surprised and weirded out by this...
I essentially saw gachas as insignificant as gumball machines when it comes to gambling, since they distribute an object no matter what, for a flat rate as little as a L$, that you could even put up for resale...
In my opinion, gambling is more toward machines like slots... A machine where you don't win anything, if you don't land on a specific set of three images... Or lottery where you just put money in and hope that Thursday you win with the randomized numbers that you picked...
Wouldn't this make more sense for Lindin Ball exploders or games like fishing for Lindin's? Or the literal slots that you could probably find scattered around SL?
I just think that the focus is on the wrong thing here if we're talking about true gambling... I don't sell gachas, but I do like going around and putting a little bit of L$ into some machines to get little things like hats or stuffed animals I can place in my place, I don't mind the randomization and sometimes I get some cool stuff I wouldn't have regularly bought...
