I have Ghost. Dont play it much. The graphics are pretty and the missions are well thought out but I like to "roll my own" and you cant beat OFP for that.
The graphics arnt quite as slick, but there is no "good-bad", you're either East, Resistance or West. I play a lot as China as they realy dont get represented much these days in the military-fiction genere. OFP also allows you to make your own cinematic intro and outros.
My favourit so far has been the SpecOps C-130 getting downed by a Strela team after making its drop. Wish I could record and put it up on here w/out needing the game to view it.

There are no less than three versions of that as a flick. The most memorable being an early 80s Kurt Russel version. Very good movies, and the oldest version is the one that "Aliens" was dreamed up from.
I second the vote for RSR, except make it into a trilogy, and stay exactly true to the book. RSR is perhapse the coolest novel I've ever read about modern warfare.
My seconds are Rainbow Six, Team Yankee and Bright Star.
