CFS3 is still rather poor (especially in the dogfighting).
A popular misconception in that CFS3 is a dogfighting sim - its NOT
. It's about the tactical use of bombers and fighter-bombers.
cfs3 is poor out of the box, granted. But with firepower and the host of user mods that are available it transforms into a very good sim indeed.
Also we now have the Mediterranean Air War (MAW) addition soon to be released - and it's free!
Gargantou - there's an excellent general cfs3 forum here:
plus the Sim-Outhouse hosts a great many add-ons.
ps. Yes you can man the gunner/co-pilot and bomb aimer positions in the bombers, in MP as well as SP, just as you can in IL2.
