When you turn off icons and have to rely on visually identifying aircraft it changes combat.
A friend and I dove into a huge furball over a base take last night. The furball consisted of 190s, 109s, I-16s, and La-7s. My friend got shot down quickly.
I downed three enemy and was saddled on the fourth when I ran out of ammo (no ammo counter like in AH). A quick look at my six showed three 109s on my tail. I extended and dragged all three to my home field as my buddy was lifting. He engaged two of the 109s and I stayed on the tail of the third one to keep from getting shot down. My buddy got one and was shot down, leaving me to fend off the two remaining 109s. After losing a large chunk of my left elevator I did a long circular drag around my field. When I had enough distance I dropped flaps and gear (takes longer than AH due to having to do one at a time) and did a rough landing, damaging my right main gear. I scrambled into a hanger narrowly missing being strafed on the ground.
The game play is there with the added bonus better graphics and aircraft system modelling.
