That would really be great, if you can focus your use case on their games, adding coin to other games would be easy once you successfully introduced your coin to them. I hope you will not focus on your exchange listing like many alts, because exchange listing will only be successful if you have good adoption for your coin. And you mention about the faucet website, you can direct some gamers to get some free coins on that site to test some games where your coin is already integrated. They will be motivated to use your coin if they will initially get it for free.
Ofcourse we are planning on adding other exchanges but for now, we're focusing on adding some real use case for the project.
Btw, we published our own Faucet website:
