If I have learned anything over the years, it is that 'EVERYONE" wants/insist/demands something different in a fight sim. Everyone's flight sim feature priority list is different. Also each and every fight sim has its strengths and weaknesses. I consider this data a fact so everyone's comments are based/reflected from their priorities and views of what is important to them.
When I see a well received feature of another flight sim that I am testing (and I own and test all the prop full function flight sim's), I start thinking about how to implement it in BOBII but I know not everyone will want the new feature. An example is historicly accurate weather (BOBII's campaign simulates the weather each hour of each day of the BOB based on weather records). Some players do not want to fly in rain and bad weather as they have other priorities (yes, it is a disappointment but a fact) so we offer options with a default which results in more development cost and effort.
I am also interested to see if ROF marketing strategy (an ex-exec software manager's fault of mine) will work (narrow base with later add on's, required internet connection, and a strong focus on MP (will the AI be effective?) and not single player).
With our base of full function flight sim's being so very small, we developers and players must learn, experiment, and test each and every one to learn their strengths and weaknesses with respect to what we want and value in our flight sim's.
