It's not a Tron game but I know blockchain cuties uses Tron as one of its currencies. I actually have a Tron wallet because of that. I haven't use it yet as I still have a little bit of Ethereum I was using for that game, but it's got Tron at least. I got a Tron wallet because Ethereum transactions were getting stuck or costing a high gas price and I heard Tron is better for scalability (in terms of the number of transactions) compared to Ethereum due to how it works. By the time I was ready to do anything else though, Ethereum had calmed down a bit so I kept using what Ethereum I already had.
