Hi, I might be willing to sell the Orange Box for the 360 if anyone is willing to pay $50 plus shipping. I bought the game thinking it was going to be enjoyable, and it is...except that for some odd reason all the games (HL2, Ep 1, Ep 2, portal, and fortress) give me headaches. (Odd, as I've played plenty of games before). Can't seem to play it for more than 20 minutes before succumbing to the headache, while I can play Halo 3 multiplayer for hours on end with no problems...

Wonder if the PC version would do the same to you?

I believe it would, I guess it had to do with the art and the way they made the tunnels/camera movements.
