I was discussing this a little bit in another thread, but I was taking it off topic. So I figured I would start a new one.
I was considering a basic Success, Partial Success, Fail, flowchart style for the Missions, if you fail at this one it leads to this, one, if you win you could turn it around, etc. Then have their objectives be things that will tie into the overall results on the front. Didn't take that bridge? The enemy armor crosses it hitting your Regiment in the flank.
How do you guys structure your games? How much of an impact do you give your players?
