Exactly. There just isn't any reason to get excited about it. And as a result, I haven't bought episode one and I doubt I'll get episode two. I just don't care.
It's not like you find out more about the story... there is no story.
Episode One reveals some of the answers to the Half-Life 2: Original Campaign....
...Though, Episode One poses some brand new questions, which most of them we're left hanging w/ unanswered.....
Only reason I bought Ep One -- it was $7.99 @ Circuit City, not too long after its release. Took me around 5 hours to finish, if I recall correctly....
I should say this: Ep One is A LOT like Half-Life 2 -- a lot of the same action, weapons, and puzzles. No vehicles, BTW. It's good, but not much is new here, really....
