I miss the days when i played Command and Conquer for hours without skipping a beat. If you're like me and want to revisit those glorious days head over to https://www.openra.net/ and check out the open source and free versions of Command and Conquer (Tiberian Dawn, Red alert) and Dune 2000!
The next major goal for OpenRa will be Tiberian Sun and i can't wait for it.
You can also follow and contribute at their Github repository which is a major plus. (https://github.com/OpenRA/OpenRA)
Works on my 21:9 4k Monitor like a treat.
