Adding more personality to slaves in the meet interaction is a recurring mod idea, but nobody has really pinned anything down yet. It's a lot of creative work to complete.

Oh, it's definitely a lot of branching statements and having to figure out which subqualities matter for which initial branches (e.g. the amount of Confidence by which a Submissive/Omega becomes notable is much lower than for a Dominant/Alpha, Fear isn't such a big deal for Doms, and Passive bypasses most of the checks I put in later by virtue of just going along with what's happening instead of actively trying to avoid it). It's taking a while to bash this out, and I'm only on the opening lines!
But I do think that just adding some alternative trait-based and situation-based content (e.g. characters speaking differently if they're Captured, which I believe should effectively act like a counter for "the first few interactions" for most slaves) will make it much less samey and more engaging. Plus, it should help me get a feel for the personality of my slaves without having to constantly go "wait, which one was the X one again?" I've especially had fun putting together variations on what Foul-Mouthed characters might say (from being rebellious through to being affectionate). My test world quickly wound up with a pair of Foul-Mouthed Dominant and Submissive, so I'm tickled that I'll get to test what happens when alphas and omegas express themselves in coarse language ^_^
