I tried MS Combat Flight Sim but found it was quite buggy and disappointing in its missions. I am an IL2 fanboy so my comments are a bit biased towards it but here goes lol.
IL2 is more of a multiplayer experience than single player, however it offers a few options:
* Online dog fighting - team up with players and conduct missions that involve dogfights and bombing missions (one teams mission may be to bomb a harbour with some bombers and others providing fighter escort - the other team is defence)
* Online Co - Op missions. You fly with team mates, all on one side with AI planes making up the rest of your squadrons (so you can give AI planes commands, like to fly in formation, break, attack etc), against an AI enemy.
* Offline missions (i) The built in missions are pretty lame but are a start (ii) Download missions from
www.mission4today.com and fly those (iii) make your own with the built in mission builder program (takes some learning but it's fun)
* Offline campaign mode. Fly a series of missions working your way up through the ranks.
The standard built in missions are quite long (ie, flying for 20 mins till you get to the combat zone) but you can speed it up. Co-ops, and online dogfighting are usually more "right into the thick of things".
Head over to
http://kiwisim.net.nz/ and click the Forum Link / IL2 forum for more info. We are a dedicated bunch of guys who fly most nights of the week. At least twice a week someone will host a co op mission and we'll team up, learning skills on a per plane basis.
It's a steep learning curve, you can play it in 'arcade mode' in single player but online servers use more sophisticated settings, such as engine management, torque and blackout effects, locked cockpits at times and so on. It took me a while just to be able to take off and land without breaking the plane. Much harder than FS to start off with I found.
Unfortunately IL2 1946 is becoming hard to find, you can get the original IL2 Sturmovik in $10 bins but it's not a patch on IL2 1946, which includes all game updates and patches.
Another game maybe worth a look is Battle of Britain II Wings of Victory (
http://www.gpstore.co.nz/Games/1472045.html) for $9.95. I have this and it's not bad, mainly flying Spits and Hurricanes. It has good game sounds and relatively easy to get into.
Hope this info helps!
