I have Falcon 4 Allied Force.
I wouldnt mind linking up with some players for a co op strike.
There were 5 or 6 guys locally I would game with, we used to play the mission where you have to disable the airfield with Durandels with a fighter cap. Great game, you really had to watch your fuel but we'd play that til the birds were chirping.
If you are up to date with the F4AF game, there have been a lot of updates that smooth out the lags/warps for formation flight.
