I think the current importance of FXCore is in this order.
FXCore Web-based Wallet - This is the most important since it will act like metamask and be able to connect to different dApps on built on FXcore.
FXCore Games / NFT - Currently, the biggest trend in the crypto space is NFT + Games.
Example: Axie Infinity
Like your ChessFX, maybe you can introduce a set of customized made Randomized Rare Chess Pieces NFT that people are able to generate while playing.
Not sure how to implement it but it is similar to "breeding" in Axie Infinity or other upcoming games.
People being able to “feature” their rare chess pieces as avatars or be used in game for the sake of appearances. Not pay2win, purely for appearances sake only, like dressing up / flex.
Something like Dota 2 Arcana or Maplestory’s dress up game.
