Since there are still some queries regarding compatibility with other mods i would like to clarify some basic questions. At first you have to remember that pure FotE without any submods is playable with some mods, but structure of FotE excludes many of them due to overhaul is pretty deep.

1. No vanilla reskins work. Zero, none, null. FotE brings many units out of vanilla rosters + replacements are very usual so reskins not dedicated to FotE simply won't be visible and if some units go replaced they mostly don't match their FotE assignement. So it won't ruin game, but wherever they gonna be placed in the list they do mess only.

2. Additional units mods, garrisons and so on - as above, structure of rosters exclude any units addons not dedicated to FotE.

3. So called "community patch" or patches. Some elements of those fixes might work, but in whole the big one version is not recommended. Only startpos.esf fixes (Gautrek fix, invisible ERE daughter) are notable here and worth considering. Remember - adding those mods exclude playing EP.

4. Animations, gore, model fixes or addons - they don't work or are incompatible. Don't try it at home.

5. Turns per year, startpos mods - they should work, but only with FotE. Startpos mods may not be compatible if they contain additional stuff that is also changed in FotE. Anyway don't try such mods neither with EP nor FotE+EP Revised.

6. FotE + EP (or FotE+EP Revised combo) - no mods are compatible besides those listed here:

Yeah, there might be some mods still useable, but i don't have time nor will to check every single mod if they work. So don't ask, don't add and we are good :).

7. You don't care for clarifications above and still want to try other mods for many or no reasons - yeah, we live in free world, nothing will stop you, guys. Just remember - placing questionable mods lower than FotE (or EP + Revised combo) is just almost full guarantee they don't ruin saves (sooner or later) or gameplay. They just won't be working if they are incompatible. But at least you save your time for reinstallation in worst cases. Placing them higher than any FotE elements brings a lot of risks, no help assured if things go wrong.

Before you place here anything check author's site to see if they don't beg for money like patreons, paypals etc. Not allowed and not welcome.

So try to avoid obvious cheats.
