And as the New Vegas modding community grows, keep in mind that many of these older mods will still be compatible with the engine as only its complexities have changed. Guns and armor will definitely transfer over, though some things like Follower mods and gameplay mechanics will definitely require another look and possibly some experimentation to identify whether or not they'll work in NV.
Keep in mind that virtually all of these require multiple, if not all the DLC expansion packs in order to function. Any other requirements for a mod will be listed on its page.
