I know what you mean. I'm not planning around own tokenomics right now. I think that's a distraction around great gameplay. Splinterlands already has enough tokenomics and more use-cases for the tokens/assets is IMO more beneficial than new tokens. (which is also difficult to get right, as you mentioned)

Re: client-side. All of the logic for the game is happening on the server. Client makes actions ofc, but those are verified on the server as well. 🙂

Oh and didn't know you're making games. Anything I might have seen already?
