OP has a good case but I'm not buying that it will make Bitcointalk great again, I guess the title is just to evoke interest and debate, and so we are having it now.
I have no problem with that, The Altcoin board is good, and rules that stipulate that it should be NFT games just as you stated, or else it will just be moved in the off-topic.
If it's added here we'll see if it really will generate traffic and interest.
But the OP doesn't want NFT games, he wants video games. His argument for that is good that he wants to attract young people between the ages of 13-21 to this forum, where they can learn about Bitcoin more and so we can ensure that the culture of Bitcoin is spread to the younger generation.
I don't know if his plan will work because adding a subgame board won't be enough to attract younger players to the forum.
