I love AF. Definately worth buying.
Operation Harvest is a great map. It is fast becoming my favorite map to play right now. The tank battles are numerous, the attack choppers dominance is nearly a non factor. I took down the Mi-28 3 times with tank rounds in one round the other day. Every round it seems like I get a couple scout & attack choppers with tank rounds, while maybe dying once from a TV missile. You must play engineer and squad up if playing armor. Stick together and don't work the roads too much. If playing infantry, go AT. Nothing scares the crap out of a tank driver than getting hit once in the front/rear tracks, and then getting toned again. Makes them get alittle nervous. Just remember, make them come to you. Don't try to be Rambo and take out a tank with a AT rocket at distance. It rarely works on this map.
Operation Road Rage initially was my favorite map of the bunch, it has moved into 2nd place. Great map however. The air threat can be easily taken of by working the Linebacker or Tungusta on the edges, in otherwords don't drive down or around the highway. Work the farthest edges without making your AA missiles blind. I recieved my expert AA badge doing this. It was piece of cake. Remember to play engineer or support while in a AA vehicle. Those missiles sure do run out fast. If playing armor, don't worry about the Overpass flag. Go around it, not under it, around it. Overpass is carpet bomb city. Stay away. Take Junk Yard or Shopping mall instead. If flying, stay high, dive bomb and get back up quickly. Had a persistant bugger the other day that thought he could fly over me at low altitude with his A10 to put a few yoo-hoos up my boo-boo. Umm. Yeah. Right. Tank rounds make quick work of any plane. Knocked him down 4 times with a T90. He eventually gave up.
Midnight Sun, love the look of the map. That's about as much as I can say. Game play hasn't impressed me much. Still giving it a shot, though. It just may be one of those maps you don't know you like until you have 20hrs in it. I have noticed the Armor in the uncaps rarely gets used unless pushed back that far. Attack choppers have more of a presence on this map than any other AF map.
