I'll be the third to wholely recommend Project Reality for BF2 and soon ARMA2. Nothing beats flying in supplies a few metres of the ground and travelling at 200MPH while that AA tries to lock on to you and those .50 machine guns' tracers fly all around you or giving covering fire for your squad medic while he attempts to revive your LAT squad mate after he ran out into Draganov field in Al Basrah as the British or climbing into a T-62 as a Chechen Milita crewman and moving up to fave a Russian T-90 in Kozelsk or Lazing an enemy FOB (Forward Operations Base) still in construction and watching as that A-10 rains down rockets, mini-gun shells, lazer-guided rockets and Bombs onto the enemy squad below or even being on the recieving end of a daring Frogfoot pilot's last act before being shot down then cowering in fear from 72 rockets and/or bombs raining down on you in the middle of a Desert. In short, I recommend this game.
