I could easily say I hated the HL series because all you do is run around and shoot. The whole game. It is so repetetive because that's all you ever do and once in a while they give you something different to shoot at. Not to mention theres no replay value because all you would do again is shoot at more stuff all over again. Worst game ever.
Except that's not the case at all. So it's a bit of a bullshit argument, really.
