As I understand it, the platform is closed; i.e. you can’t get the word out any other way than buying the platform’s own advertisements. And even I am wrong, and you can, the overwhelming majority of people don’t look at anything else than the platform’s own ads for choosing what game – I’m sorry, “experience” – to play. The platform does not make it easy to see good games, only the top played games and advertised games. The platform lures developers in with the promise of a large audience and a chance to get huge amounts of money if their game becomes popular. But the only games becoming popular are those for which developers pay the most for ads. Therefore, it’s exploiting developers’ drive to make good games popular, by requiring them to pay for expensive ads.

Bonus: Now, since most of the developers on Roblox are kids, replace the word “developer” in the previous paragraph with “kid”. Does it seem exploitative yet?
