💡 Beginner Tips
- Use a mod manager like Nexus Mod Manager or Mod Organizer 2 to handle the file structure, as manual installation can be messy with multiple folders.
- Check the mod's compatibility with other popular New Vegas mods like Project Nevada or FWE, as old mods often conflict with gameplay overhauls.
- Since the mod is from 2011, consider using the New Vegas Script Extender (NVSE) and the 4GB patcher to improve stability with larger worldspaces.
