There are some of the blockchain games which start out with NFT then they get into the games. And later they add more things like staking, rebuilding and also making the modifications. So that kind of adds up on the games improvement part. I have noticed recently one such game that - Gods and Legends. It has everything on the stake, NFTs, build and the trade items in the game as a part of economy.
NFT giveaway is also in the process. The NFT would be released to the lucky winners based on the draw and they have usual conditions of upvote, tag and retweet. I think that's kind of common for games these days to push the promotion. It's on the WAX chain and the NFTs would soon spread across the other chains.
Create a powerful deck and then get the opponent in the match. The game would be loading more of their comic elements named Angels and Demons into the collections. So they are not just typical NFT and the game but instead they have this comics and also other things that you can do in the game like staking your tokens and then building the NFT value.
It has another series on the Binance smart chain named - Angel and Demons. There is also the tower defense game in the series lined up. So you may want to explore that option too. Some of the time what happens is that such games become too much cluttered. But this has been going on slow and steady for their ecosystem. But I am not sure if it is churn worthy. But my opinion may vary based on what I see in the community.
You can keep a tab on the game if you are into such type of the games. I am sure you would find this game pretty good and also worth playing.
