DCS and MSFS are two very different sims. MSFS has the advantage of superior scenery and detailed dynamic weather, as well as the potential to simulate civil aviation in stunning detail. The flight dynamics for such aircraft also has the potential to be extremely good, when the top tier quality payware finally arrives. DCS on the other hand simulates military aviation on a very high level of detail, with advanced combat simulation. There are no real way to compare them. The price of top tier addons for both are expensive, as they are very complex and takes a long time to develop, just wait till you see the price tags on PMDG’s airplanes… DCS can be bought at half price though, if you wait for a sale. Well worth it in my opinion, I have bought pretty much all the modules over time during sale, sure it’s expensive if you buy everything at once, but buying 1-2 modules each sale makes it manageable.
