I got DCS 1.5 recently and now after buying the F-15C and SU-27, the F-5E is a must buy. IMO, DCS has a ton of potential and already a number of great aircraft. For starters, I am going to spend most of my time buying/using the Jets, primarily the Mig-15, Sabre, F-5E & Mig-21 (aside from the F-15 and SU-27). Down the road a bit, I will buy the WW2 modules (and scenery as it becomes available). With the significant list of models that are coming, I think DCS has and will continue to establish itself very well as a combat based sim. This sim for me brings back memories of the days I used to use Falcon 3.0 (which I used far more than 4.0).
