This is something like what I've been envisioning as well. A huge realistic MMO where everything is NFTs. A fee of all sales goes to the developer to keep things running but everything within the game is player run and owned.

basically on market there are same games appearing all the time, in my opinion its because game creators are scared to face already existing big companies and titles.

I think this is much due to game developers creating games for publishers on contracts. If we had more indie devs we would see more innovative games which we do from time to time. Those big companies only think about the money and make what the crowd likes.

go and fight him, steal his car, steal his girlfriend.

lol

I think something like what you're envisioning here is the future of gaming. Let players get something really valuable back for their time. In this case NFTs and crypto.
