Lasereth, You can change the difficulty anywhere. No need to play through the whole thing on the same difficulty. I played on Hard for most missions. I turned it down to normal on a couple of missions that I just didn't want to fail again. If you play on Brutal, you'll want to save your game every couple of minutes because things can go from well to fail in seconds. Having that recent save can prevent a lot of frustration.
