NFTs have a place but it isn't central to the Internet. That was hype to separate idiots who didn't know better from their money, aka grifting, and that kind of grifting has used literally everything to do that same thing in the past so NFTs are not a unique tool to that end.
NFTs have no place at all. There has yet to be any good suggestion on what they should be used for that isn't served by something else just fine. Or if not "fine", then at least solves no problem that would make it better. Not in-game items, not ticket sales, not silly ape pictures.
Why would a game company prefer to distribute their game with Steam instead of as shareware? Also nothing about having an NFT-based ownership license to a copy of a game precludes it from being on Steam except Steam not wanting to have a secondary market. Outside of a bean counters ledger there is nothing incompatible with them.
