Is there a fun style of expert play *other than* no-loss?

If you establish universal unit weights, they woudlnt need to be perfect.

You have to start somewhere, playtest and revise.

This is the way to create a new artificial limitation forcing you to adapt in a new way.

You suggested that artificial limitations arent helpful but "no loss" and the various difficulty levels of the game are in themselves artificial limitations.
