I can't say I know much about blockchain games or what their future prospects are, but even if they were scorching hot right now, it'd still be way too early to add a subsection. Same thing with NFTs. Can you imagine if Theymos had added an ICO child board back in 2018? ICOs were a popular fad, but that's all they turned out to be, and it took quite a bit of time to determine that. In hindsight, currently irrational people might come to realize that there's nothing special or collectible about digital art that just happens to be linked to a blockchain. See my point?
TBH, I'm just afraid that we (as a forum) will be left behind because we don't want to follow what's happening out there, if we don't keep up with the hype, we won't even get a glance. I mean, don't be too conservative about Bitcoin, this forum can move because of advertisers, campaign creators and users right?
The statement from @Mahirap below might be a consideration:
The more this blockchain gaming will be popularize the more topics and discussions will created on this forum. Also, developers and companies will come here to advertise their games.
It is true that nobody here on the forum will want to be left behind in time. And I think that in general this has not happened.
Now, the issue with NFT games is that almost all that exist, the focus is not on the game but on making money with a token. Ending up looking more like a system to earn money than a game.
Nothing against the money making factor, what I regret is that they use the term game for this purpose. When most of what exists has little to no gameplay. And that's why they are only really profitable when new players are coming in, when that's over, the game almost disappears.
Therefore, it is difficult to distance these NFT games from other altcoins. And while it is like that, perhaps the emergence of a new board dedicated to this topic is more difficult.
