I recently had to take a look into the current state of SD+ and it sent me on my usual ADHD tangent. See, current generation of prison/enslavement simulators doesn't really deliver, prison escape simulators won't work either. Sooo... how about a simulator of being at large?

Step 1: get yourself enslaved - the usual way. Probably you will get all forms of predictable abuse - it doesn't really matter, because the real game begins after you escape. Possible masters for this idea are limited to bandit leaders, city nobles and other folks who can believably arrange a hunting party. With you in the leading role. The next depends on where you escape from. Countryside masters will literally hunt you. With dogs. City hunt is more gumshoe-themed: placing bounties, asking around in taverns etc. Arguably there should be separate hunting mode for mages, but at the moment I have no idea what that could look like.

The hunt is limited, but not by time. There is a budget of certain "heat units" that work not unlike the way sneak is leveled: units are spent when they are breathing down your neck. In other words, if they are hunting for you in the woods and you are hanging around in a tavern the counter is not ticking down. The side effect of having high heat on you is that fast travel (both by map and by carriage) becomes unreliable. Every now and then you will end up right where you don't want to be.

Now, how do you avoid capture? Often you will be able to simply outsneak or outrun the hunters, especially if you clock serious time with SLUTS. "Rule one: cardio" But then consider this: slave boots distort your footprints, rubber catsuits (or certain animal secretions) mask your smell, blindfold hides your identity in cities... you get the idea.
