How much money did Half Life 1 Make to date? With all the repackaging, multi consoles, and the people who bought it just for the mods they could play?
Imagine if HL1 was in the same situation, I mean for software that may have costed 500,000 to make how much revenue was made on the first Half Life? If that was stolen and put onto the market via other country's low lifes how much money would Valve loose?
If the pictures are to beleived, Half Life 2 is already on shelves in Russia and anyone who has purchased it is not giving any of the money to Valve that they deserve for the time and effort to produce the game.
Theft is Theft, and it's already costing Valve money, maybe not alot of money but it's still costing them. Not to mention the money I'm sure they've spent into not working on the game and completeting it and new networking security etc.
Find the bastards that did it and use them for a real world display of physics

Like say... when a person is pushed off a 10 story building lands on a car and then bounces off onto the street.
