Early investors that do have the courage to test early beta games will always be benefited if the said project will be hyped. But it needs money to start and face the possibility that they might not get the ROI. Most NFT games now are hyped at first and only a few got become stable in the long run. Cryptoblades, Alienworlds are those I played during early access exactly right from the start of their game launch but after their hype was gone, it now becomes a usual game that exists in the NFT game world.
There's nothing to be worried too much though, yes there's risk in this games but it's a matter of gambling for this kind of stuff and you don't want to miss out on big profits because you're playing too safe. Those games that you've played, at the least you're still making money from it since it's stabilized and it didn't crash and got abandoned.
