http://www.fallout3nexus.com/downloads/file.php?id=2626 seems very interesting, but I'm wondering if it's compatible with FWE 5? If so, guess I should use RaiderMercenaryExpanded[M&W].esp (as I'm using both MMM and WMK) - and the load order is pretty obvious as well as it must load after those two. Also, I wonder what you guys think of it?

Yeah, that mod's going to overwrite a lot of the changes to those factions introduced by FWE. It will certainly work, but you likely won't see those factions with the FWE weapons or stats. Plus, the new content they will be uses (weapons + armor) won't be balanced to FWE's standards.

With a little work in FO3edit you could probably make a compatibility patch pretty easily though if you wanted. Not too hard to merge the leveled lists and/or adjust weapon stats.

I use it on some of my non-FWE characters and like it fairly well. It's nice having extra armors and weapons for the enemies (and for me to loot from their bodies) to break up the monotony. Bethesda Ruins becomes a lot more interesting to invade...

Thanks for the info. I think I'll skip it for now.
