If they make their own smart contract then there is no doubt about it, they will become one of the major competitors of those platforms. I think they should focus on the transaction speed and gas fees if they wanted to overcome the popularity of the current huge platform of smart contracts. Meanwhile, they need to have partnerships and use every connection they have to link their smart contract to some of the leading NTF games out there if they wanted to be known faster than expected. There are millions of players and each of them is looking and wanted to have fewer fees and speed when doing transactions.
