how to play with out origin

Command & Conquer 1, Red Alert 1 and Tiberian Sun are all freeware, so they can all perfectly be played without Origin. They have also all been upgraded with community-created unofficial patches that fix a lot of their bugs and compatibility problems. You can find them here:

Command & Conquer 1:

• Complete No-CD game installation pack (v1.06c r3, no videos, all music included)
• English videos pack (French and German video packs are also available on the website)

Red Alert 1:

• Web installer/patcher

Tiberian Sun:

• Full game
• Patch

For the other games... uh, that's just to confirm your ownership. You can perfectly allow it to remember your login, so I don't really see the issue...
