I was also looking a clip of Portal 2 not a FPS but is is a First person kind of game and twisted 3d puzzle...

Portal 1 sits in my top 5 single player games of all time, the combination of writing, game play and comedy come together beautifully. Some people complain that it's short but I think it's just right for the type of game that it is, any longer and it would have become too repetitive.
