I was browsing the contents at Board Game Geek, remembered a few similar things and though it would be a good idea to bring attention to some of them.
Doom: The Boardgame
Deckmatch (Quake)
Fallout: Warfare
Fallout:Paper & Pencil Get it, read it... it's awesome.
X-Com:Tactical
Starcraft: The Board Game
Starcraft: Spawn The cards could be improved... 
...but the overall idea is nice.
Halo: The Strategy Game
Warcraft: The Boardgame
And (dis)honorable mention...
Simcity: The card game Apparently broken... pity. I remember a card game with similar general idea. That was just plain addictive.
Do you know of any interesting video-game-based boardgames? Or perhaps have the idea to make one? Post here!
