Dude, why build this on whaleshares or Steem, unless you just want access to the community? You could integrate it into Ethereum via Loom or your own version of Loom and reward people with NFTs and fungible tokens.
All you need is for people to verify their account by signing with metamask, then you don't have to worry about junk like RCs and people's assets could remain off-chain until they care to store them on Ethereum.
I can see serious potential for FPS NFTs, like guns and stuff. It would be awesome and if you used Loom you'd even have access to the Loom Marketplace for selling digital guns, knives and stuff. You should totally make a gun called the Betonator...
Interesting, EOS was my first consideration, however, I didn't think about your NFT idea :) Thank you for that, you are right. I don't think either blockchain is necessary, perhaps just make the logins open ended, and reward in NFT's :)
All is very new in development, including myself haha
Just a thought, feel free to ignore of course, but find me on Discord if you have any interest in working together :) You seem to know a good bit about ETH.
Actually, doing some thinking, both whaleshares and steem are better platforms for this. We have community, we have currency, and we have bandwidth. Why would it be better to pay another chain to use theirs? (Honest question)
You could do the NFTs for the weapons etc, similar to how splinterlands does cards on steem too.
