It'll be interesting to see if this sort of stuff gets popular on Bitcoin. Obviously it would make more sense to use Bitcoin for everything than other crytpos, but Bitcoin wasn't made for this sort of thing. I guess with Taproot Bitcoin can now start being able to handle simpler finance applications better. But to do this sort of stuff - games, NFTs - I think that would never be possible on Bitcoin because it isn't designed for that. So you have to rely on sidechains. But then a sidechain is sort of like using another crypto network, except you still get to use Bitcoin.

Not sure if these sort of applications will ever take off on Bitcoin because I'm not sure people will ever really bother using sidechains much. Now if there could be an open application layer built on top of LN that including NFT funtionality (have no idea if this is even possible), rather than having to go with one of these sidechains controlled by companies which is pretty much no different than altcoins, I think that could have a possibility of being something big on Bitcoin.

Anyways, yeah to build an NFT game on Bitcoin you gotta go with a sidechain but the downside is they aren't very popular.
