#46 Size Matters, this franchise hasn't seen many AAA entries, but this entry was one of the first to introduce Xbox Live.
It was one of the premier Xbox exclusives. It had one sequel, and then it seems MS gave up on it unfortunately.
#45 This PC game features gameplay including time travel, nukes, super weather machines, mind control and various other weapons of war.
It was a sequel to a highly successful RTS game. The amazing main theme to the soundtrack also got a sequel.
