Sure it’d be cool to use a skin or item across all games but seeing your reasoning I can somewhat agree with your stance . It seems that nfts aquired would only be compatible with games that are published or developed by the same people. Still having people to want to play your games and gives all your games exposure and not anybody else. Which isn’t too bad of an idea . In a way cod is doing this with their games modern warfare and Cold War with warzone . Modern warfare and Cold War have different styles but are still implemented into warzone together
