Seems like the only "utility" is hope - hope that an $80 bet turns into more.
Current market value is at ~$600 and it's a playable game with actual users getting regular updates. It's more or less the maximal value of all NFTs I can remember right now.
It's about as much utility as one of those Wii figures for $40. Why don't we simply appreciate that some NFTs aren't total bullshit but fun tech toys?
