[H] Half-life 2 [W] Offers

I have a 2nd copy of Half-life 2 lying in my inventory since some years and I don't know what to do with it.
Let's see if someone is interested to this game.

Also I want to share with you a mod called "Black Mesa".
With this source mod we will be able to play HL1 trough the source engine. The release date isn't known, but it definitely looks interesting.

Perhaps you may be interested in Half-life 2 if you don't have any source engine based game ?

edit : I forgot to say that I don't want to trade for keys.
edit 2 : The game HL2 has been traded.
