P-39Q, yes, add it. We need more planes in general.
B-29, sure, whatever. Add it, perk it, no nuke for it. Problem solved. Let it exist, not many people will use it up where it was known, because they want to drop their payload, not fly for an hour, just climbing.
Pe-2, yes. Very yes. Even better. Pe-3 bis. The fighter version, with 2 20mms and 2 12.7mm guns. Slightly faster than the standard Pe-2.
Tu-2, yes. It's just good. No two ways about it.
I could go on and on about aircraft I want, or just think we need. At the end of the day everyone wants planes they like. And I don't see anything wrong with that.
If it is possible, I wish that every aircraft from WW2 that fits the requirements should be added. Why? Because there is nothing wrong with that. It would give experienced MA players more choices in the MA, and would make the Snapshots/etc much better. And open up more choices.
I was reading an old Air Warrior Site a while back, and they were using the Zeros as Ki-43s.
And though Aces High is not Air Warrior, I would prefer to use Ki-43s as Ki-43s. So why not just add every plane (that fits the requirements) to the planeset? Who cares if it 'impacted the war greatly' or 'didn't actually do anything.' Just add EVERYTHING, that might actually make most of us happy.
Who cares if something is a Hanger Queen. Better to be a Hanger Queen than not an option, at least to me.
