I know the game is old but I have a quick question.
When playing the single player game do most people turn off the in-game intels (IFF type diamond markers, highlights, etc...) This is done by holding "X" and selecting the diamond to toggle them on/off.
I found that once I could figure out how to turn them off, about 3-5 missions in to the game, I kept them off till the end playing on "Normal" difficulty. Was this what most people do, or is it considered "fair" to leave them on?
Thanks a lot for the advice.
