Got the Gekko's despite No Gekko's bug, then noticed I'm a release behind! Time to update.
I'm not using FOOK, or XOV, or whatever those are - yet. I've just returned from not playing Fallout3 for several months (in fact, I stopped playing just before the GECK was released, I think). I am using Very Slow Leveling LITE, though.
I'll tell you what, Very Hard is indeed approaching what it should be with your mod. What's killing me is: ammo. I can usually out-smart the AI (like that's hard

Increased Increased is hell on wheels, though, and at times overwhelming. My 6th level character was heading for Minefield to complete that portion of the Survivalist's Book quest, and I ran across the abandoned church SW of it. I swear, the svcker had at least 15 Super Mutants either in it, or wandering about, and three Centaurs. I really didn't want to bypass it, and had some hilarous fun luring a group of 4-5 Mirelurks into there (they and the SM's had a little party) as well as a band of raiders (who got eaten alive). Four of the SM's were of the Brute variety armed with Miniguns. Whew.
I finally had to bypass it, despite the piteous cries I was hearing from their hostage(s). Well, good! I don't like scaled encounters, or, at least, not constant ones - running into areas where I must retreat is something I like. The numbers are also increasing my crashes, though, so I did have to lower them by stepping down to Increased Spawns.
Some minor stuff:
1. Molerat's teeth: I leave those where they lie. Just too weighty and not worth much - 2lbs per set and only 1 BC.
2. The custom loot all use the Deathclaw model when sitting on the ground - is another, perhaps smaller available? Minor quibble.
3, I also have had encounters where creatures with nearly full health go and cower.
4. Fleeing creatures make the UPP's Coward perk tempting
5. Do all creatures have like an enhanced Sneak or something? My character's Perception of 7 is not picking them up as often as he should, I think . . .
Kudos for the author of the Night Ghouls, too - they are frackin' AWESOME. Scared the crap out of me the first time I was jumped by a band of 3-4 of them.
