Is http://planetelderscrolls.gamespy.com/View.php?view=OblivionMods.Detail&id=2000 compatible with Oscuro's?

Most, possibly all, of the modules would be fine. Having said that, there are newer and better mods which cover much of the same ground. Personally I only use The Realistic Law Enforcement modules now which, in conjunction with some other mods, are a replacement of sorts for RGO.

It will work fine probably if you put OOO after it since MOE was done very good and doesn't have any bugs, the scripts are light and I have a feeling that overwritting something from MOE with OOO shouldn't cause much trouble but if you use MOE after OOO it will probably cause your game to malfunction because OOO isn't stable or reliable do you understand? At least tell me whats the list of modules you are gonna use from MOE.
