What has changed since 2007?
Thinking more along the lines of the strategy side of things.
Kev, not much in a positive way.  The de rigeur of captures is now to bust all the hangars while busting the town.  A far cry from, vh, deack, cap, and capture.  I keep playing because of the friends I've made.  It's nice to catch up with them, and laugh.  
Whether it be air or ground, "fast and furious" sums up what I see as I fly past to pork or bomb something.
Oh, busting hangars things also can have a 30 plane noe component to it also.  Not my cup of tea.
Nice to hear from you.  Hope all is well.
