hi all,
I am gonna get BD tomorrow and was wondering whether to choose action or strategy difficulty? I really want the game to be very challenging, but not to the point where it becomes frustrating...

I am not a newbie at this kind of game, I finished DD and found the demo really easy, so I guess strategic would be the best choice?

oh yeah, is there any way to disable being able to change the difficulty in-game? I really hate being tempted by it, it feels like cheating and it takes all the fun out of difficult situations if I know I could simply lower the difficulty...
