I agree pay to win games suck, its the one feature which will make me instantly drop a game. But pay to win isn't gambling, afaik you can't earn robux by wagering robux you can only earn worthless in-game rewards.

You don't have to win money for it to be gambling. If there are cosmetics someone wants but has to pay for only a chance to get them then it's gambling with the value they are betting on winning being the cosmetic they want to win.

No, it's straight up gambling mechanics. Open any trading card game and tell me that it is not filled with mechanics that effectively resemble gambling.

You don't need to "wager" robux for it to be gambling. You pay real money for robux (or whatever intermediate "currency") then spend robux to buy lootboxes (for example) which then by having very bad odds to get the thing you actually want, counts as gambling.

How are loot boxes different from slot machines? The underlying psychological mechanics are very similar if not the same.
