I was thinking how it would be cool to develop mobile games that uses the same hooks the pay-to-play ones use. But instead of it being revenue, that money is invested for the player and they get it back later when they're more lucid and less gambly.

So people who have addictions can scratch that itch like they normally would but it wouldn't wreck their finances. Most investing needs a lot of personal information which is too much to ask for I think. Storing their money like a bank is too much responsibility as well, when they buy credits or upgrades I'd want those funds going directly to the investment package. It could be too complicated of a problem to solve but I would have no qualms copying the popular loot box games and taking their customers away if the reward side could be easily set up.
