Description
Old World Blues Mod : w/ Music, interesting add-on mods, and maybe more decisions

Remember choose either ONE of the expanded mods:
  • Expanded plus
  • Expanded plus (non enclave)
  • Expanded plus ultra
  • Expanded plus ultra (non enclave)]

If you don't like Enclave that's fine. Don't subscribe to
  • Enclave Reborn Redux
  • Enclave Officers+
  • OWB ERX Enclave Facilities
  • OWB ERX Sigma Intervention
  • God Bless the Enclave
  • ERX Super Events
  • OWB ERX Ship and Unit Names
  • ERX Universities
Despite what you might think there are Enclave nations in default Old World Blues, so the radio mods do give ambiance to the default Enclave nations.

If your game runs slow unsubscribe from:
  • East Coast Rebirth (Adds Fallout 3 in the East Coast)
  • Rustbelt Rising(Adds the Midwest, Beware Chicago)
  • OWB - Fountain of Dreams(Adds Florida)
  • OWB - Monarchs and Margaritas(Adds nations to cross into Florida)
  • OWB - New England Rising(Adds nations in the New England Area)
These mods are pretty heavy to low end pcs.

If the collection is a bit too difficult, there are other OWB mods that makes it easier.

Want a challenge? Max out all the countries difficulty and choose the Enclave (Above New Reno) and when a decision comes up on how hard do you want it to be choose the hardest option. You don't rebuild the US as the Enclave unless you fight tooth and nail for it.
