My first kid had a real problem with wanting Robux, it’s all he cared about, I dreaded even hearing the name Roblox and never played with him. 10,000 arguments later and he was over it. He introduced our younger kid and stressed to him that “Robux are a scam” on the first day, and it’s now one of my favorite games to play with him and he started on Roblox Studio a few weeks ago. The older one doesn’t play much anymore but he’ll join us occasionally. it’s sad I missed out on all the fun with him because of the obsession with Robux and my inability to distract him from it. I think if I had just played with him, he might have not have cared so much, but my hate for it from all the fights stopped me from even installing it.
How are they a scam though? If you can buy ingame things that bring you joy it's not wasted money. You just have to set reasonable limits so you don't end up spending 100s on silly things.
Scam's not the right word but you start to run out of accurate words when you can't get your point across after having entire days ruined arguing with a screaming kid about a R$10,000 Golden Dominus that would cost $100 USD to obtain.
