I am not sure about such investments, NFT for gaming is just hype now, but this sphere is not a limit for Non-Fungible Tokens. It is better, to my mind, to look for projects where NFTs are used for documents and data but not for just entertainment.
But, on the other hand, I can be mistaken as we don’t know the duration of this hype so if you can earn now then try.
You might be able to try other alternatives for projects other than NFTs but you are avoiding the popularity where the era of NFT has grown rapidly so far even gamers have earned a lot of money from NFT, we have to adapt to developments in crypto including for hype which is not liked but make it fun so you are motivated to achieve the main mission of taking advantage of all the hype.
