an emphemeral L3 that last for a full event like a game or tournament. do a ton of onchain activity / let users earn tons of NFTs, then at the end, let them "export" their favorite things / summary NFTs back to L2 that live forever.

Honest question - what's the benefit of an "L3" here?

If the event span is shorter than the time it takes to play exit games, then why not just have a server and post selective data to L2 at the end of the event?

L3s don't have to be optimistic w/exit games. could do validity proofs. or could even just do a trusted commitment at the end from the operator. 

benefit is:

0. use L2 assets
1. write everything in EVM 
2. integrate seamlessly with other EVM tools
3. everything is open and onchain

it's gradually going to "just work"

I thought another huge benefit of L3 was that gas fees can be drastically cheaper than L2? So many more txns can be on-chain than were feasible otherwise? Or is that not the case

You don't get another factor of savings when you post to L3 vs. L2 because the "compression" from a validity proof or from posting calldata can only be gained once

Savings could come from more efficient VMs or using alt-DA layers, but those savings could also be gained at L2. What L3 really allows for is *flexibility*
