I'm finally well enough to play some Tempest Rising.

It's a Command & Conquer Red Alert/Tiberian Sun mashup homage that's using Unreal Engine. If you played any of the Command & Conquer games, you'll feel right at home. Especially if you look at the story and controls. Not to forget the cut scenes. There's also multiplayer (that I haven't tried yet).

I love it so far. It's the first RTS I enjoyed since Earth 2150 and Warhammer 40k Dawn of War.

Love these base building SciFi RTS games. Good dose of nostalgia.
