The AI, hands down. Not because of their dumbness, but because of the weird things they're allowed to do to overcome their limits. It breaks immersion all the time. I hate specially the hyperdrive jump effect for friendly AI when enemy appears, and the Robocop right-between-the-eyes AI gunners.

1. No fear for AI.
2. Crashing in the forests and getting killed in plane explosions - about 1\3 of all pilots who made a forced landings in the forests were alive. Exploding midair in an airplane did not mean getting killed either.

You dont flyh with your hands on the throttle? Even when I used a lone MSFFB2, before I got the HOTAS bug... I kept my l hand on the throttle..

1.) Character models are pretty bad. Would be nice to see better animated pilots/characters (humans) and overall more realistic looking characters. Especially in the bombers the character graphics are bad and have not been upgraded since original IL-2.

2.) Buildings/scenery. These must be redone in the next IL-2. Way too primitive looking. But not so detailed as to hinder framerate.

3.) Music. More selections and overall better music score would be nice.

4.) Realtime cloud movements. Clouds that actually MOVE and cast their respective shadows would be brilliant.

Bear in mind that this sim is 6 years old.. the engine is 10 years old.. I think it is Pretty good in that respect.. At least here you can put your own face in the pilot.. LOL.. I thought that was so cool.... As good as the AI si thyey are my biggest beef.. When I tell my wingman to cover me or help me or attack enemy he should go for the one closest to him.... but too often they pass up the one next to them to go after the target I am on and I wind up getting nailed.... Oh well... Oleg said BoB's AI will be better...

for a 10 year old sim engine it is wonderful... :)

Rehashing things that aren't going to change. Ever.

to be able to fly all the AI aircraft, with a cockpit!

fix some sounds I need this game in 5.1 surround sound not just surround sound.
