considering all the factors when transferring the money? it'll cost a lot and we can get to the point that's not worth it if all of the transactions are on-chain. I guess LN should be applied to this...
Yeah, right. There's also a server that already existed called BitQuest (also in MC) with the implementation of LN on that server. Only a few people know about BitQuest since it was made during the early days of BTC and now they aren't existing anymore.

SatoshiQuest creator says the transactions are done on-chain and the game will reset after finding the loot.
Will this kill his idea? I don't know but; since Lightning Network is there, I guess it would be better for him if he had implement way to use Lightning Network.
