Going on twenty-five plus years and NO ONE it seems is able to code AI that don't go stupid or lock onto the Player exclusively.

Have you never played Battle of Britain 2 from A2A? 1 vs 1 AI is pretty darn good. I have flown the Spit and the 109. IIRC, the Spit has to work pretty hard to beat the smartest AI 109, while the 109 is a little bit easier to fly against the best AI Spit. Massive single player missions with tons of bombers, escorts, and interceptors are simply breathtaking. I am disappointed that they didn't apply the same upgrades/fixes to MiG Alley and that they never produced the planned P-40 AVG / Burma version of BoB2.
