phd_doc, check PMs please.
While the DCS environment will be as you saw in DCS World (exceptional graphics), the fidelity of the Lock On aircraft will be similar to that Su-25. Having played with a fully-clickable cockpit, I find it easier to remember WHERE a switch is located and click it rather than having to remember a myriad of keyboard combinations. In other words, with a fully-working cockpit, I only need to remember the "important bits," which is usually on the HOTAS 90% and the rest is easily accessible with a mouse click. The rest of the "advanced functions" I just need to know where they are.
I do not understand why some think that DCS A10C is a "difficult" sim to learn --- the excellent built-in tutorials and the even-better online (YouTube) tutorials make learning this sim very easy, plus the active online community makes finding a "mentor" to show you the ropes is also not a problem. (You guys should see the state at which BMS is in!!) I have always said that with a minimum amount of reading (just to familiarize the cockpit) and 2 hours in the air, a new pilot can go from green to I-know-how-to-blow-stuff-up-and-this-is-awesome straight away. DCS simply offers a lot more DEPTH but it is up to the user how much time he needs/wants to invest in the sim. New pilots can always start on a warm jet or use the "cheat keys" to start up quick. Being able to create your own waypoints and route from the CDU is cool, but new pilots can always leave that for later. Air-to-air refuelling teaches fine control of the aircraft, but with the efficiency of the A10s engines, this isn't really necessary unless the mission calls for crossing the entire map.
The important bits that pilots need to know --- take off, navigation, dropping ordnance, navigating back home, and landing --- very easy to do. Two or three sessions with a decent instructor is more than enough.
Basically, doc, what I'm saying is don't let the perceived complexity of DCS A10C or DCS BS2 or even Falcon 4 BMS deter you from having a go at those sims. You can be up-and-flying in no time, you can be killing things after a few tutorial sessions, but these are the types of sims that keeps you learning and learning as you go along. However, the "fun bits" of making things go BOOM! is only going to cost you a quick few hours of your time but the will keep you hooked in for months and months afterwards!
