Disallowing gachas is just insane. What is wrong with this world? This is madness.
They're not bad.
I have occasionally enjoyed buying gachas, because they're fun, because it's a surprise what you will get. Mostly i don't like the rare ones, i'm happy with what i get and i know when to stop. The cost is usually very very low and if i use a bit more on some gacha, i'm happy to give the money to creator, who has used her time to create the stuff.
What is so bad about them?
Don't you have those gumball machines and toy vending machines, do those machines make monsters out of kids or adults who use them?
This just makes SL and using money here a bit more less interesting for me.
I don't like how shopping oriented SL is, every fair or event is almost all about shopping stuff, but gachas have been a fun exception.
And i don't gamble. I don't get why you call gachas a gamble. There are similar games (games of chance) in amusement parks too, are those to be closed also?
