Have you tried Gods Unchained? They have pretty much pioneered quality NFT gaming to the point they created ImmutableX to deal with tx fees for nfts. I think they are definitely worth looking at even though i have some personal issues with them, ton of communication issues during launch and deceiving technical bragging. I don't even need to understand the whole issue, i trust way more tech savvy coders than me on that. But i recon you get best experience for investing very small sums in any game and not try to free leech them. You can get so much more from them when you have skin in the game.
