so if the game is fully onchain, there is no server running the game

think about the scale of the game then

I am a wealth of knowledge - unfortunately my knowledge is useless | Game Designer | /sands-of-sumaii

My criteria for fun farcaster games that I've been brainstorming:
- something social that takes advantage of notifications and open social graph
- can be played asynchronously, scaling to an infinite number of players
- easy to understand (ideally familiar) 
- free to play with optional onchain mechanics that heighten gameplay

I like building crypto apps and learning new things.

Personally I still see that as optional. Ballframe was a small scale game but I was genuinely surprised how many people were willing to pay to get their score on a leaderboard.

That being said trading/economies is a natural extension for crypto, I just think (maybe hope) that it's not the only one

I think another criteria ought to be:

- must include trading of assets

I think that's one of the main benefits of web3 gaming - economies. The other one is persistent onchain worlds, but that's waaaaaaaaaaaay harder
