New to the boards just finish hl2, episode 1 and 2 and now want to play the original half life. but someone told me that xbox360 won't work on the the original game. So do I have to buy the first xbox now to play halflife? Oh yea, who the heck is gman? That dude kept appearing at weird times during gameplay and I never could figure out what he wanted or was about. Thanks in advance?
