Question regarding keys and the Ultimate Collection
Command & Conquer 1, Red Alert 1 and Tiberian Sun are all freeware, though, so I doubt these will matter in any way. And Red Alert 2 and Yuri's Revenge on Origin was a free giveaway, so it's honestly rather irrelevant in this scope.
All games starting from RA3 can be redeemed on Origin with their product keys. I doubt they'll just give you their newer games for free, though.
Though as for the missing RA expansions...
Well, back when they made C&C1 and RA1 freeware, the expansions were never included. However, the Tiberian Sun expansion was added. This made a bunch of people in the community realize that they most likely either just forgot about the earlier ones, or just thought they were insignificant because they were 'just mission packs'. Either way, it didn't take long for them to be included in fan repacks of the freeware games, and as far as I've seen, no one at EA ever minded this. The official C&C website even promoted my C&C95 patch despite my explicit mention that the Covert Ops was included in the patch.
So yeah, just Renegade left, I guess... I dunno, if you don't want to buy TUC, maybe you can find it on ebay?
Anyway, for Command & Conquer 1, Red Alert 1 and Tiberian Sun, I just advise getting the freeware downloads. All three of these games have also been upgraded with community-created unofficial patches that fix a lot of their bugs and compatibility problems, and the C&C1 and RA1 patches actually add higher resolution support. You can find them here:
Command & Conquer 1:- Complete No-CD game installation pack (v1.06c r3, no videos, all music included) (also contains bonus missions originally exclusive to the Playstation and Nintendo 64 versions of the game)
- English videos pack (French and German video packs are also available on the website)
Red Alert 1:
Tiberian Sun:
- Full game (scroll down to "single player, patches, linux and mac" and select "Single Player Campaign (Windows)" in the dropdown)
