Will I lose all my saved games if I start a new campaign in Rage?

Solution 1:

The quick answer is no, you will not lose your saved games. What you will lose is your current auto-save, as can be seen by the following screenshot:

You can see that while I am at the game's very beginning, which is where the current autosave is, I still have my saved games from a later stage.

When you choose "Continue Campaign" from the main menu, what the game does is load your auto-save. When I loaded one of my later saves and got to the point where the game auto-saved, continuing the campaign loaded that save, instead of putting me at the beginning (where I ended up until I did that).
