I would classify myself as an axis-oriented player. Nothing specific, I just like the planes. Now, Guppy, I wouldn't say no to something with spitfires, BUT... it would have to be balanced. There was a window in WW2 history where the LW had parity or superiority to the RAF aircraft. If we just start throwing Spit16s against 190A5s you know the outcome before you start.
So, as always, it boils down to individual setups for any given scenario. Example: The Final Battle did not interest me.
I guess... In short... any scenario that I join!
