I was setting up NV again for a future replay, and thought I would put this here, in case anyone wants to use it. Basically, to improve NV combat, the key thing is to remove hitpoint bloat, which turns it into an actually enjoyable FPS combat system. There are mods out there that do this, like Project Nevada and JSawyer's mod, but people might not want to use them because they add a LOT of stuff, and you might not want to change so much, or might be playing it on an old computer. So here's a quick way to remove hitpoint bloat in pretty much the same way that Project Nevada does it, but in a simple tiny mod you can make yourself in about 10 seconds:
Install NV, download GECK (NV version) from Bethesda, load NV.esm file in GECK, and under Settings, change 4 variables:
fAVDHealthEnduranceMult: health multiplier for your endurance, change from default 20 to 10 (or less if you want)
fAVDHealthLevelMult: health multiplier for your levels, change from default 5 to 0, to stop gaining health at level ups
fAVDNPCHealthEnduranceMult: same thing as above but for NPCs, raise from 5 to 10 to make same as yours
fAVDNPCHealthLevelMult: same thing as above but for NPCs, change from 5 to 0, to stop NPCs from gaining health from extra levels
Save as HitPointBloatFix.esp or your preferred name and activate in data list, and voila, you've just turned NV into a game with exciting FPS combat. Add No Neos mod from Nexus to get rid of NPCs dodging bullets, activate hardcore mode to stop stimpak abuse, and don't use VATs, and you are good to go.
