I actually rather enjoyed Red Alert 3 a lot, and I loved the older series, especially the original areas and Generals. C&C 3 and 4 are the only disappointing games in my eyes, but while I could overlook 3 I could never forgive what happened in C&C4. I'll give them one shot. Tiberium is done for, Red Alert is pretty much summed up for the most part. Generals needs a remake, ASAP! So much story left open, such amazing game play that allowed for massive base expansion and limitless amounts of units. Chaotic fun of 4v4 games of modern armies massing hundreds of tanks, soldiers, and one Air Force support-style roll ally bombing from the background was a massive blast.
I loved being that support role, by the way. Air Force General is the only way to go, baby!
Remake it now, and as long as you follow what they did in the original Generals, I'll be a happy as hell fan.
