EA releases original C&C games for free
Command & Conquer 4's out next month, and to get you pumped, EA has released the original C&C games for free.
These include Tiberian Dawn, Tiberian Sun (with the Firestorm expansion), and Red Alert.
Red Alert and Tiberian Dawn have been free for a bit now, but new to the freebie end is Tiberian Sun.
BigDownload notes that Tiberian Dawn requires a separate disc virtualization program to load the ISO files, so that may or may not be an issue with you.
