There are several Second Life games. Where you pay L$ for something and then you have to actively play their game for you to even win back or obtain profit. But for that to happen could take IRL Days or Weeks for basically Chump Change.
For example in SL there is "Virtual Fishing" you can optionally pay for bait and you fish virtually. And that the fish are only worth 0.3 Lindens sometimes 0.6 Lindens sometimes more sometimes less. It's completely random. And these fishing events / spots are to increase Sim Traffic. Getting lindens from these places are always random and very time consuming.
Even something like Breedables kinda follow this "it's gambling" because Certain Breedables are worth more than others due to their RNG Genes, traits, and colors.
And the sad part about breedables is that they need to be rezzed 24/7 for them to age or progress and at times these breedables have 20+ even 100+ prims.
That's a lot and to add further insanity is that you need two of them to breed. So double the prim count and possibly the cost too. TBH I think Breedables are worse than Gachas.
Most of these Loot Boxes and Gacha bs could have easily been solved, if LL just said that Gachas must include the Odds of obtaining each product from Gacha Machines. And possibly provide a Pity Pull which some Gacha creators have implemented in their machines. Incase if someone had "Rotten Luck"
If the odds were displayed on the Gacha machine maybe there would have never been a ban on them in the first place.
This is just an example.
Commons 70%
Uncommons 23%
Rare 5%
Ultra Rare 2%
Some laws state that this is a requirement for loot box systems or in this case RNG items must show the odds / chances.
I don't think it's fair to boot one RNG System such as gachas. When there are Breedables with RNG Traits and colors. For example I saw these cat breedables that look like they were made in 2004 "Primmy" "Dated" and some of these cost 5k or up to 15k just because they have a specific rare pattern, trait or whatever..
and you also have RNG SecondLife activities that reward you a fraction of a linden that requires hours of active play.
