It's no Falcon in terms of avionics, but radar is there in several modes, and you can lock targets up, however it's not anywhere near as complex as the real deal. Similarly the attack modes are limited too, for example there is no DIANE system on the A6 Intruder, which means good old dive bombing or well timed level bombing is the way to go, although guided weapons such as the Shrike and Walleye missiles do lock stuff up and guide, as do the Sidewinder and Sparrow AAMs. Ironically, the weapons do look very convincing though and the pyrotechnics for them are among the best, looking very much like the real thing and the AAA and SAMs are scarily convincing, with some real 'wall to wall' flak when you go on a mission over Hanoi or Haiphong Harbor. Air to air gunnery is good too, as is the damage modeling, which is remarkably complex for what is essentially a 'lite' survey sim, rather than a study sim.
Also on the plus side, there is a huge array of weaponry, with everything that was ever conceivably slung under a plane in 'Nam there, and it's all usable. It runs well on fairly modest computers too.
Despite its simplicity in comparison to Falcon, there is a great feeling of immersion with it and not all aspects of it are simplified, for example, the carrier operations are probably done more convincingly than in any other simulation (and that includes Janes F/A18), so succesfully 'trapping' on a carrier is hard on full flight realism and feels like an achievement (which of course it is), although you can just end the mission without trying it, or land on autopilot if you don't want to go that hardcore.
The flight models are good, and generally suit whatever plane you are in, although the helicopter flight models in the Yankee Air Pirate add-on mod have been acheived with some programming trickery, as the orignal flight model engine did not support helicopters, so they do handle in a tricky fashion and are not as easily 'flyable' as say, the ones in MS flight simulator.
Most Third Wire sims are limited in their support for online ops, and WOV is no exception to this, other than the fact that, unlike some other TW titles, it will allow you to do co-operative missions as opposed to the more basic 'online dogfight' scenarios more prevalent in other TW titles, although it will do those too. So while it isn't up there with Falcon's superb options in this arena, it's still capable of offering some co-operative online fun with your buddies, and it runs great in that mode too, as evidenced by the screenshots on a previous page of this thread, picturing a couple of A6 Intruders in close formation, where there was no 'rubber banding' from lag, or aircraft jumping about to make life hard.
If you like just ticking a few options boxes and then getting straight into the action with minimal fuss, WOV will do that for you, and also do a more in-depth campaign where you have to manage who flies which plane in your squadron and which aircraft they will take, and there are aspects such as a limit on munitions available and a finite amount of available airframes, so you can make it more realistic if that's your preference. It's in no way as complex or as groovy as Falcon is where the campaigns are concerned (but then again, probably no simulator is or ever will be LOL), but it's still fairly good and historically accurate too, with only the right available aircraft appearing at the specific dates for what was a ten year-long war.
Personally, I like it very much, but that might be because I'm particularly interested in the air combat aspects of the Vietnam war, so it would be hard for me to not like a sim which caters for one of my interests, nevertheless, the modding community for Third Wire stuff is strong and has improved it beyond its original form, and Third wire's support for it's products is right up there with the best, with the developer easily contactable via the forums and willing to consider improvements and suggestions from anybody.
In addition to this, with the 'supermod' that is Yankee Air Pirate, it ramps things up considerably in terms of realism and could fairly be regarded as 'the GWX for Wings Over Vietnam' (although unlike GWX, it aint free, but it isn't that expensive either and can be purchased in small modular chunks, which is an innovative approach to add-ons).
Ultimately, it's up to you whether this kind of thing is for you I suppose, but I suspect you probably would like it. see the other thread on this forum for some more info on it and a couple of links to some videos I made with it.
