OK heres my problem, I want to get Half Life 2 but i travel between two states alot. when iam at home i have a cable connection, but when iam at work (other state ) i have no internet connection. So iam wondering if i buy the game will i be able to play when iam without an internet connection? should i just say screw it and get Far Cry or Doom 3... been playing both demos and now since i have a computer that runs them they are more enjoyable... anyone have any input???
