That article is pretty comprehensive. Thanks for posting.
Highlights from that list are probably the Rise of Flight WW1 sim and DCS A10C.
The new IL2COD and Jet Thunder promise to be good once released.
The Rising Sun (and Yankee Air Pirate) addons are very well done considering the resources the guys have.
A couple of recent addons for Microsoft FSX are the A2A Simulations B17 and new Spitfire Mk I and II.. These are modelled with realistic systems (unlike most FSX addons) and are a big hit with the rivet-counting flight simmers. I've read forum posts with users comparing cylinder compression figures on their damaged Merlins...
Cheers!
