Enjoyable. Definitely worth looking into.
The one thing I really have to comment about this game is it's prolly the best music that C & C's made in a while. When Yuri's Revenge came out it obliterated the good soundtrack for something that sounds like a dog urinating on a light pole. I'm sorry, but this version blows away the expansion sound-wise.
Another thing to like about this game is it isn't all based on Tiberium Wars and things like that. It's based on a war that on a relative scale could have happened for real (obviously not accounting the mind control, killer Tesla, and Terror Drones, lol.)
One last couple of things. You have got to love the Campaigns of this game, they are verrry interesting and you get a feel for the side you choose. If you like power and offense, then Soviets are for you. If you like intelligence gathering and things close to that respect, then Allies are good to go.
This is one of my fave old-skool war games and if you play it, it might become yours too.
