At some stage when you're not fielding all the "Add me! Add me!" requests, it might be interesting to be able to further filter the data by game. For instance, comparing my ratings with Morente's it *looks* like I give higher ratings to T1/T2 missions than they do, and they seem to rate T3 missions a bit higher than me. It'd be interesting to get a better look at that data.

Yeah, this is something I've changed in how I build my own fan missions. I no longer include no-KO or no-kill objectives unless they're specifically story related (don't kill the guy you're trying to kidnap, don't let the watch captain know about the breakin, that sort of thing).
I also won't force combat or blackjacking; there'll always be a way to ghost it.
There's a couple of things that go into this.
First, getting through a whole level undetected and unsuspected provides a real sense of satisfaction.
Second, blackjacking guards throughout a mission makes it easier as you progress. So you have this weird inversion where the difficulty ramps down instead of up over the course of the mission, and finishing it feels anticlimactic.
Third, you're not supposed to get spotted. It's kind of the point. If you alert guards, sure, you can go on ...
