An NFT is superfluous here. If you buy a digital copy, and someone gives you DRM-free files that you can copy and run anywhere you'd like, you have about as much ownership as you can get over a digital good. In this case, an NFT would just serve as an entry in a crypto ledger that you bought the game... which is an alternative to running a digital storefront and tying game purchases to an account, but it doesn't really change the fact that you can only redownload something for so long as it is hosted at the place where you bought it.
