I've been on DCS on my new PC for a few weeks(which is actually only a few hours I grab when I can) and have been learning the systems on the F18-C. Definitely not a game in the normal sense of the word as to get into the fun stuff of shooting down people (I'm coming for you Zac Yates....) yiu have to learn how to use the radar and HUD as well as how to fly the thing! A bit easier is the Spitfire IX. It is not easy to fly initially as there is quite a bit of tweaking for the primary flight controls. Plus if you dont fly it like the real thing you will stall it, spin it, over heat it and get shot down.....a lot! Everything works like the real thing and if you havent got the rudder trim right on take off? Off you go into the weeds. It's frustrating to begin with but satisfying when you get it right. Yesterday I managed to land although did damage an aileron and ended off the side of the runway. But the engine still ran and the prop wasnt damaged! Sorry the photos are linked as logged into Flickr on my phone and I dont seem to have the choices to upload. flic.kr/p/2kSMrja
You either get a Russian scheme or RAF European with it but you can upload other schemes. Chap on the NZ Australian DCS Group is going to upload Al Deeres "AL" scheme so I'll have to get that.
It's very realistic. The F18 now has pretty much everything working like the real thing (apart from secret squirrel stuff). You need to devote a lot of time to learn all of the systems but it's up to you how much you want to learn to have fun online. A new update has just come out and there's been a visual update which makes it look even more real. VR is next from me as the ability to just glance around the environment will be fantastic. Not cheap though!
The Auster should be recognised for what it is: a gentleman's aerial touring carriage and a nice aeroplane.
