Well, I beat fallout 3 and knew that you were supposed to make a separate save file before the final mission. However, I forgot about that rule in New Vegas and now I'm stuck in Legate's camp. It kinda svcks...
Does anyone know how to fix this? Or if Obsidian is going to release a DLC like broken steel for new vegas where you can continue on with the story line?
What do you mean "stuck in Legates camp"?
Also (1) there are several key moments when you chose to do one thing or another before you arrived at the dam, surely you have a saved game from before some of them?
Also (2) If you're still in Legates camp you haven't made the final decisions yet.
Finally, there's a mod that allows you keep playing on which works very well if you haven't explored the entire landscape yet or done all the side quests.
But the fun of the game is creating a new character and making different choices right from the beginning IMO.
