I FINALLY got my ideal endgame scenario for this game
It was EASY, all it took was 4500+ hours of restarts, crashes, bugs, crashes, save file corruptions, crashes, loading loop bug, crashes quest breaking bugs (caused mostly by the Tunnel Snakes CC content), crashes and some more crashes.
Good thing I never encountered any crashes during my 4500+ hours of playtime for this game, not even once.
Now I just need to FINALLY explore the restored Vault 120 cut content mod. With Big Daddies instead of Ghouls or Mirelurks.
