Mideast Crisis 2] (MEC2) is a total conversion for 'Command and Conquer 3 - Tiberium Wars' set in the near future, letting you use modern technology (such as the Abrams, F-35 and Hind) alongside future technology (such as Drones, Airships and Medibots) in a conflict ranging from Jerusalem to Beirut.
MidEast Crisis 2 really takes its predecessor into a higher level with more fun. I can't say more.
Only one thing in my mind though; the contents may be a bit sensitive to some religious "hardliners", but nevertheless, the mod is very good.
