If p2e game devs can make something like GTA 5 it would be celebration day for crypto and p2e genre, such feat would bring millions of gamers in the world to the crypto.
But tbf, I don't see this happening anytime soon. It would be better if AAA games implement crypto elements into their game by themselves. For example, to buy cs:go skins with crypto would be nice or marketplace where people can trade their inventory items with others with payments in crypto.
But if every single player is only after the financial gain they could get then where that money will come from and how this model could be sustained for the long term? This is the question those developers always avoid, and that is because they do not really have an answer for it.
