Generally the same as splitter as far as campaign interest and variation is concerened. I don't have the time to do my own campaigns but I did on the old CFS series. The only one that I did that was different required pilot 'decision making' based on real time events. Mission success was based on not killing a 'friendly' which is the opposite to most campaign missions. In a nutshell, I used moving enemy armour to set the time limit and these would surround and over run an allied position if not halted. If the enemy ground armour reaches its objective you will certainly kill a friendly and its mission failed.
Pilot decisions involved selection of route, ground defences, etc, identifying the target zone (Damaged C47, palls of smoke and allied light armour dotted around it) wether to engage/assist/evade when the flight was intercepted. On reaching the target area - observing which of the flanking enemy columns posed the most immediate threat, were there any targets that could prevent their progress. It all took time - and there wasn't a lot of it......anyway I am wittering so will get me hat and coat..........
