I feel like a total chump asking this -- but is there any other way to save my game besides Quicksave and auto-save? Like... can I manually save my game? It seems really weird that there isn't a Save Game option in the menu. In case it matters I have my old CD copy and am using the "unofficial" 1.1 patch.

Yup, there is. Press "escape" to enter the menu, then click "load save", and you'll go into the save menu.
In fact, I didn't even know there was a quicksave. I use this one every time.

LOL, I honestly read it as just "Load Game" -- thanks for setting me right!

Yup, "Save / Load" would have been clear, but "load save" is just confusing ^^
