Just finished the campaign and gotta admit I really liked it.
Like the C-101 in general, it really teaches you stuff and enforces good airmanship (the IFR navigation in mission 1 was already discussed in this thread, but also the combat missions later on when you are just given a VOR radial, DME distance and intel picture of your target - at first they seem daunting, but then you realize its really all you need to find any AO ).
Mission 10 especially is brutal (but from the briefing and voice comms its also made clear that it is supposed to be like that).
I lost all my wingmen at the first engage because they are immediately shot down by the AAA trying to do traditional dive attacks (poor guys, think they are supposed to be the fighter pilots I trained before , but then again I know the AI problems are in the game engine and can't really be affected by mission makers).
The most effective way to take out the 4x AAA seemed to sneak up through the valley at ground level, short pop-up, taking out a single AAA, then back to ground level maneuvering left/right to (hopefully) evade the fire of the remaining AAAs that at this point have turned towards you.
Even then I had to fly back to base and rearm once, since your rockets and gun seem to require multiple 100% on target hits to fully destroy them. (or maybe my aim just is that bad...)
So in general a wonderful campaign that really tingles the "I feel like a better pilot now" feeling when you succeed.
Everything seems to still work as of late 2024, its mainly the last mission that might seem disproportionately hard - but as I wrote even that might be by design to force you to get creative.
