I recently saw that there's a vote going on for Ra2 to be added on GOG.
Ra2 has already got quite many votes and it would be cool if you could add yours
GOG (good old games) is a quite well known game platform that does not use DRM.
Here you can give a vote: http://www.gog.com/wishlist/games/command_conquer_red_alert_2
Also consider voting for this. Everybody would benefit
