It sux and is awfully hard to fly in a multiplane enviro because of netlag.

But from what little I tried of AH (il2 is the real thing imho), it didnt feel that much woser in ww2ol/BE. Plus taking part in a 30-40 men/plane bomber mission to Conventry is a huge feeling, well until the Spis/Hurris/Dewos show up over England and the whole thing turns into a series of still images because of netlag, and you keep struggling in your 110.

When there are only 4-5 planes around, its nice.
OTOH, no other program offering such a detailed damage simulation and land enviroment for ground attack. It's the tanker sim part that's awfully good, plus the pure feeling and the mature playerbase.BTW, you can try it yourself, the whole thing can be d/l for free and tried offline.
