A lot of blockchain games are created purely for making speculative tokens for pump and dump schemes, so essentially they are just using Steam to advertise their investment scam.
This sounds like a valid reason also justify the steam's action of banning blockchain based games. How a platform will accept to keep on hosting "planned scams", if you ask me, any reputed services will take similar action in favour of their customers.
Steam's ban on blockchain games should not be left out like just another incident in crypto space. It is kind of alarming to this community like scams on crypto space is exceeding the tolerable levels. This way major service provider also may ban all kind of crypto activities when they find 90% of new projects are not keeping up their promises.
It is as simple as that, a centralized service like Steam has to protect their reputation and if some developers are acting in a way that could damage the reputation of their platform then they are within their rights to ban the game, and if a whole subsection of games are doing that then they can ban the whole genre of games that are doing it, and if to this we add those games are producing a lot of money and Steam is not getting any out of it then this is an even more powerful reason for them to ban those games.
Yes, it's a standard procedure for Steam to restrict blockchain games because they risk damaging their reputation as a gaming platform that focuses on reviews of actual gameplay. Because p2e games may quickly destroy the standard of the game, and most reviews will likely center on how much it will earn rather than how excellent it is.
I'm also against it because I'm a gamer and, of course, I play p2e games, but if I want to play a good game, I'll look at how good it is, but when I'm looking for a p2e game that gives fast roi and profit, steam isn't the best platform; instead, create your own platform or app that will launch the game. Steam is purely for those games that are all about enjoyment.
