I've been trying IL2CODTFMATAG server and it makes a nice switch from AH3 but it is a difference that works for me and maybe not everybody, If I had to give up one it would be the IL2. Whenever I have tried WT I didn't like it, simply can't see the point of the arcade modes and the FRB type thing....I guess I didn't have trackIR and I couldn't really enjoy it with the view mechanism and a hat switch. I don't like the idea of upgrades and experience levels for gunners, I just want to fly the effing planes. The guys on the ATAG server seem like a nice bunch, one guy sent me a track IR3 and another a hatclip and they refused postage! It is very different than AH3, there is only one terrain (It is basically the end of the battle of france, BOB, and operation Sea Lion) with fixed objectives for a rotating list of missions, no icons, you can easily blow up the german engines, you've got to stay on top of prop pitch and manifold and radiators a bit, very limited plane set, I have no idea how you use the bombsite, I need the trackir they gave me, teensy populations, AI flying fighters and bombers, occasionally dubious flight models, no visual radar or information about where you are on the map, you slosh around in the cockpit quite a bit, slightly lousy control setup control, etc etc. And for me a biggy is there is no ALT-X to let you run to the bathroom or give your arm a break.
From a user interface point of view AH3 is superior. The only thing lacking is a good comprehensive indexed/searchable manual. The information about the game is a bit diffuse and can be difficult to track down. WT I found hideous with too many steps between logging on and flying, and a bunch freemium nonsense clogging up the works. The only thing I would add to AH3 is something like the single player individual missions in IL2COD. Pre-scripted Icon Launched Air Start simplicity to basically practice maneuvering and shooting at AI aircraft.
I'm guessing that the people that actually LIKE WT enjoy playing a game about flying while the people who like AH Warbirds IL2 etc. want to fly. (The tanks....well that's another thing altogether.)
I'm not deluded enough to think that flying ah3 is like really flying a high performance airplane but with these things you bring your own fantasy and suspension of disbelief with you and I think it is frankly easier for me to suspend disbelief with a joystick, rudder and the AH view system than it is with mice or game controllers or even trackIR. Maybe it is the reverse for somebody else who isn't hung up on interfaces or has a younger brain.
