Not that I care about these titles, for context. I was under the impression one, could download them from any source for free offline enjoyment. As many in series were dumped into open source.

edit, added a useless word that broke my sentence

EA released the following ones as freeware :
- Command & Conquer Tiberian Dawn
- Command & Conquer Red Alert
- Command & Conquer Tiberian Sun (incl. Firestorm)

These games can directly be integrated in client CnCNet.

CnCNet also supports RA2 & its expansion (Yuri's Revenge) but the client does not come with the game. It needs to be purchased separately.

Neat. The more you know :)
