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.
Is it insulting to all of us his assumption that for Bitcointalk to be great, a non-Bitcoin or Cryptocurrency should be added, Bitcointalk is still great, and a platform is non-existent in the Crypto ecosystem unless it's introduced here.
What you've recommended is good on the Off-Topic board, any industry that has and will have a section here partake of the reputation of Bitcointalk and not the other way around.
