I guess Soulbound NFTs are a thing beyond Splinterlands. Veefriends was the only other NFT project I had gotten into in the past given my admiration for Gary Vee. I got into his Book Games with very little luck but also bought a Series 2 NFT at some point as I liked the art. Neither have really done much for me although the community remains quite engaged as they crossover between virtual and physical things very often (last I saw was comic books).
The platform recently made a shift to a more centralized platform and outside of the Layer 2 option they had with IMX. As an incentive to move, they offered a Soulbound NFT. There was really little option but to make the transfer so I did it despite knowing that it would not be worth much. However, it is another lottery ticket I will hold on to given how strong I feel the community truly is despite the challenges of Web 3 and NFT over the last couple of years.
