Terrain
According to this sim there's not much flat terrain in the Scandinavian countries so you kept it over 5000 ft.
Canards, ailerons and rudders moved constantly in flight. This sim immediately upped the ante as far as realism in terrain mapping, containing Norway, Sweden and Finland rendered in amazing detail for the time.
Eric Dahlbeck, a resident of the region, tells me:
❝Southern Sweden is farmlands very much like southern England (more yellow than green though) with some forests here and there... They have taken the landscape of northern Norway and put it all over Scandinavia.
❞ Ok, well then if not geographically accurate, it definitely represented a quantum leap in PC sim scenery at the time of release.
