I am mostly interested in ONLINE mission building. While IL2 has a fantastic mission building tool for online wars, RB was really quite limited.

Anyone heard anything about KOE?

I would hope you could make your own custom servers and coop missions. I would really like something better than either IL2 or RB.

Some thoughts:

Ability to give an airbase a scramble %. ie, if you approach an enemy airbase there would be a % chance that you would trigger enemy fighter planes to take off and pursue you.

Ability to place your targets where you want them.

Wide range of target types.

Choose what planes are available at what aerodrome (and what would really be nice is to be able to limit the numbers of each type).
