You may be wondering why some mods aren't in the guide, or are looking to add your own mods. If so, please reference this list:
WMX/WME: Incompatible with WMIM, and even if they did work they still need a lot of balance work
More Perks: Countless broken perks, bugs, spelling/grammar errors, and more
CAGE - Continue After Games Ending: Old and broken, replaced by FPGE
NV Interiors: Causes save bloat due to the large amount of havok-enabled items per interior
Classic Fallout Weapons: Has many broken weapon meshes and breaks some leveled lists
Primm Reputation Restored: Does not function properly, also impossible to get idolized because of oversights
Simply Uncut: Most of the stuff isn't cut content, but rather fan-made versions of concept art. Also lacks quality in many places
New Vegas Landscape Overhaul Remastered: Will cause crashes due to broken navmeshes
Outside Bets: Has some poor implementation of features that will result in bugs, also requires a good bit of conflict resolution. Useable if you can put up with that
A World of Pain: Awful balance for the entire mod, un-lore friendly locations, no voice acted NPCs, no room bounds/portals in interiors which can cause FPS loss. Also useable if that doesn't bother you
Monster Mod: Bad meshes for many creatures which can cause crashing, terrible balance
