DamirH is correct it appears you don’t understand how the gaming market is being attacked right now on sites like Steam. People create few nice looking screenshots out of assets from Unity or Unreal Asset Stores which they copy past over 50 times to create 50 " unique games " spoowing all of them to Steam hoping that one of them will sell atleast few times as at then its worth it.
Just like Kickstarter is losing the potential donators because of some many thiefs promising mountains just so they will get the money and run away with as little spend on the actually project as they can. We as a developers who have very limited resources have to protect sites that allow us be connected to millions of players that can potentially buy our product.
Unfortunately, it is true that people from countries where 500 $ is above the monthly minimal wage (like me in Poland) will have a problem to enter to such a market. But considering how many low budget sites are on the market that allow us achieve same resoults as we would have on steam just in much smaller amount, it is not much for people like me to just safe the required money. True it would take some time but if you really want to create and sell a game project it is normal to actually spend certain amount of resources to actually start.
I prefer to save money for 4 months and release it on a quality location like steam than spending zero and release it to the site with hundreds of theft project HOPING that someone will believe me that I don’t want to robe them of their hard earn money, but rather share my work.
Everybody should be allowed to be a game developer as everyone has amazing ideas talent and creativity BUT like to everything in your life if you want to put your heart into your work then you should trust it enough to risk at least 500 $ to put it on the market.
