There are boxed versions available for Rise of Flight, for DCS Black Shark and even Flaming Cliffs 2 which is an addon to a sim from 2003. Other 1C titles like Theatre of War are also available as boxed versions. Just because Oleg says (IMHO correctly) that sooner or later niche titles like flight sims will be available through download only (as is already the case with most indie games) doesn't mean we're there yet.
Then again this forum and some special members in particular have always been eager to draw premature conclusions
