Instead of just outright dying and getting a 'game over'.
Why not have some other sorts of consequences?
You get beaten down, but make it back. News and gossip will spread and the girls will fear you less.
But, what encourages people from not just reloading it? You still get something out of it. Maybe bring that one item you found back, that super duper one or a slave rag. Maybe one or 2 men from the gang also survived, instead of wiping, dragging themselves out with you... or being the ones who drag you out.
Right now though, once you train them past a point, they don't need your help and its very unlikely that you will wipe.
