There are already many decentralized games in which the function of exchanging for example TRX for internal game tokens is implemented, but this is not enough. Therefore, I think that the STONE platform will solve a number of issues related to the exchange of tokens and increase their liquidity.
I prefer Ethereum over TRX as it suits me better. If the STONE platform is implemented, it will greatly facilitate the use of cryptocurrencies in decentralized games.
