To celebrate the launch of The Orange Box, we're giving away a copy of the game which started it all (in a way), Half Life 2!
(The fact that we already owned HL2 before purchasing TOB and therefore have a spare copy is purely coincidental.....

)
How do you win it? Simple - simply register for our
Steam Community, then PM me with the subject line "Half Life 2 Compo" including your Steam ID (especially important if it differs from your username here) and a 20 words or less answer to this tiebreaker......
You should give ME the free Half Life 2 because.....
You have until Sunday night, at which point the best answer will be picked and one gift copy of HL2 passed on! If we can't pick an answer by ourselves (we don't agree on much, really) then we'll put it to a vote here.
So get registered for our community, then get your thinking caps on, and good luck!
