IMO it's great but it is a departure from earlier titles in more than just going to 3D, and the sides are a 90s caricature of the US/China/Middle-Eastern people, so it's something that you definitely couldn't make today.

Like the "terrorist" side gets suicide bombers and a unit called "angry mob" to which Chinese flamethrowers or American snipers are a good counter, while China gets two soldiers for the price of one and propaganda loudspeakers everywhere that makes units fight harder.

The story is barely there as well, which was a strong point of the RA2 and Tiberium universes.
