C&C3 is pretty good decent story and lots of replay vaule, C&C4 is worth Playing once, Great Story but once you beat it on both sides it Sucks and has no Replay value cuz the story ends once and for all, Like i said its worth Playing, but i sugjest you know a friend who has a copy and they let you play it, even if you find C&C4 for 10$ trust me its 10$ cuz it has Absolutly no replay value after you do see both Stories..
