There is one simple solution which dates back to the C64 era.....Easy, medium, hard. It eliminates strife between casual and hardcore players.

For instance, Il2 sturmovik had a such options that you could set very easy gameplay, or if you wish you could ruin your nerves with realistic plane behavior, no external views, no markers etc...

By my opinion one of most important traits of simulation or any other game is openness and simplicity for modding. SCS software (Euro Truck Simulator series) live from this feature more than a decade now and they have truckload of customers. On other hand King of the road and Rig n Roll were quickly gone to oblivion because poor support and rigidness toward any modding except sounds.
