Thanks for letting me know about RKR!
Might be just the thing. I'll try it, and see how it goes.
I'm currently using FWE (along with tons of other mods), which - I believe - includes Arwen's AI improvements. And overall I think that's a good thing; don't get me wrong there.*
However, I can still, from a distance and when stealthed, one-shot people (in the head, generally speaking,) and those around them will move around a bit more at times, act a bit more cautious for a while perhaps, have a half-hearted look around... but that's about it.
What I would like to see is what is likely to happen in reality if someone suddenly keels over, their head somewhat splattered, with others nearby. IOW, people freaking out ("What the ____ ?!"), doing whatever they can to find out what the heck is going on and where the bullet(s) might've come from, seeking cover, etc. Those who happen to be armed, well, they might do mostly the same, but also be looking for the next convenient opportunity to fire back, of course. And I don't see
why they would forget - not for hours, at least. I mean, would you?
For that matter, more or less the same (if a little less dramatic) should probably happen when folks come across the fresh corpse of one of their own.
Maybe, I guess, stealth is just too easy. The character I'm playing at the moment isn't even remotely specialised in that, and sometimes does "sniping" in full daylight with no cover, without even so much as a scope. All too successfully, at that. Haven't died once so far, and she's heading for level 6 soon.
* Thnking of trying ART in place of FWE some time, in fact. I still find a
lot of things far too easy. ART + RKR, if that one works out.
