Yes, right now, probably not, because the tech is still in its infancy stages and it's a bit of a nerdy niche. But it's growing all in all and I could see it play a bigger role in the future. The Altcoin boards is of course a very messy section and I rarely put my foot in there, however there are some interesting projects and services, where you are actually able to use your crypto and not just watch them sitting in your wallet and waiting for moon magic to happen. Gaming is one of those use-cases, but it's difficult to monitor things when these boards are all-in-one boards. But I also understand that Altcoins are not top priority inside this forum for obvious reasons.
I admit to not having downloaded and played the game, but I can only imagine that this is valid for just the beta to attract players. In the full game, you would have to at least pay for transaction fees. And then as you can see on the homepage, you can buy certain packages etc. So, yes, maybe you can play basically for free (i.e. only paying transaction fees), but you won't get anywhere with it, because you will always come up short against players that do actually invest a bit of money. In a play-to-earn game, it is not possible or would make no sense to be able to earn money without investing anything upfront. Where would that money come from, when everyone can play for free but earn money ? The profit of one user is the loss of another user. Unless it's a charity game of a wealthy person
