Well here is my 2 cents
A friend of mine who has deep pockets has
G2, AFP and XTR

IMO just by using the three ( about 2 -3 hrs on each )

G2 is the most unrelistic of the three. OK graphics . Maybe with more tweeking you can fix that

XTR has the nicest graphics not bad for realism. BUT because of the graphics you really need a high end
Graphics card. So with a XTR and a graphics card it an expensive sim. Unless you already have a card.

AFP is the most realistic . OK graphics. The least expensive of the three . Runs Very nice on a low end 128 mb card

AGAIN there are IMO with little time on each
