I had some thoughts regarding aircraft naming and their upgrade paths that I think might be useful to discuss in this thread.
First, I think I saw that Vokarya doesn't like using national specific names, so to eliminate some of those the names below could be used to rename current aircraft:
IL-2 to Dive Bomber OR Fighter-Bomber
A-10 to Ground Attack Jet
P-59 to Subsonic Jet Fighter
OR P-59 to Jet Fighter and Jet Fighter to MultiRole Fighter
Second, on upgrade paths, they don't currently really match how these aircraft were actually deployed. I think a better model for how the planes were actually used would break them into 3 trees ( they could probably keep current unit categorizations) that would be Strategic Bombers (shortened to bombers below) that would be the type that would focus on bombing cities, factories, large armies, Ground attack/Light Bombers/Tactical Bombers that are more focused on taking out specific targets, and fighters:
Bombers: Blimp->Bomber->Strategic Bomber -> etc. (Ie, remove IL-2 from this path)
Ground attack/Light Bombers: IL-2 and Seaplane -> A-10 -> Stealth Fighter (despite the name it is not used in a fighter role)
Fighters: Remove Stealth Fighter (F117) from upgrade path
3rd, and probably the most difficult, is it possible to scale aircraft range by map size, and does it seem like a good idea?
Sounds good to me, especially rescaling aircraft range by mapsize
