First off, the apauling launch of WWIIonline 5 years ago is compleatly irelavent. Its nothing like the game it was back then and its just pointless going on about it.
The developers know it was a disaster launch, everyone that played knows is was a disaster launch. nuff said.
I played Aces High for 3 years and to try and compair the 2 games is pointless as well. they are totally diffrent except for the fact that they both are circa WWII and have aircraft in them.
Aces High is a WWII online flight sim that is all about the air combat and not about being historical. Spits against Spits, 109 against 110's (bar the special maps)
WWIIonline is a combined arms WWII sim and is all about the historical. which is why some say "Axis is biase" No its not its just most folk are used to perfectly balanced equipment like in AH where you can go 190 against 190. WWII was not about balance and in the early years the Axis DID have an advantage, but the guys at WWIIonline did a good job trying to get the early yeasr as balanced as possible. Your supposed to use your equipments strenghts.
WWIIonline has come along is huge leaps and bounds, there are no longer ditches along every road, FPS is far better (i get 50 on avarage over a large town in a large battle) Graphic wise, just like AH they have limits due to the large viewing areas, but again has come on in leap and bounds.
WWIIonline is a VERY good MMOWWIIsim, even the reviewers on many sites and magazines are giving WWIIonline 8 out of ten, which when you realise it is a very niech market is a real good score.
Aces high is prob the best WWII air combat sim there is.
WWIIonline is the best combined arms WWII sim there is.
Is AH fligh model better than WWIIOnline? depends who you talk to. For me you never seem to be flying at any speed in AH, in WWIIonine you really zoom along the contryside.
As for the track IR thing, WWIIonline has had track IR support for ages
If you want to whack WWIIonline, fine, but at least have a more up to date opinion that 3 yeasr ago.
I poped back in here to see how AH 2 is looking, nice to see the same miss-informed opinions are still rife on the boards.

You can donwload the whole game and practise offline for nothing, at least do that before you rubbish there efforts.
