As well done as those mods and conversions are, a DCS quality level F-16 sim would totally overshadow all of them. The quality levels with each of those is so varied that it's distracting and all of them "feel" old to me.
Not to mention for someone new coming into the mods they have to track down and buy a 13 year old, out of print, $60+ price gouged game just to use the new mods while at the same time not getting confused with available retail F4:AF which looks like it's the same game but won't work.
All good products, but none of it compares to a DCS module.
