Pros: Very well done in all aspects.
Cons: The only down side is it will take some time for new users to master the controls. Not that the controls are rough or hard to use, but there are a great number of controls. Don't get me wrong, once you have taken the time to get the feel for this amazing space flight sim you will have alot of fun with it.
Other Thoughts: The graphics of this are simply amazing. All flight models are extremly well done. Inside each craft there is an array of displays for almost any guage needed for spaceflight. The controls will take some time to master, but once you've done that this space flight sim will keep you occupied, and interested, for long periods.
