Well actually failure will occur if there is only one scenario/map available and The Channels or "la manche" is a good example.. It is a great scenario but really fast boring to global virtual pilots. A map a scenario that is well suited for many fights and a good terrain relief.
ROF for example understand this quickly and now adding more maps.
DCS 1944 must do the same. even a Pacific scenario would do good. but a real good is for example the Eastern side where "sport" dog fighting were happening.
