I already owned a copy of the original title a long time ago and its a great game.
Good graphics, sound and gameplay (even though its really only a Command and conquer type game with bells and whistles).
I wanted the expansion packs though and at 6.99 for everything it seemed a good deal.
You cannot install these seperatly though as it all come on one disc with these included in the main install.
I have to say that applying/ downloading the patches which you are forced to do is a pain in the ar*e. I also originally had problems doing this, but did get it to work eventually on my laptop.
I had to also create a profile and password to actually play the damn game as well.
Good game though especially at the current price.
