Well, we all know that the source for HL2 is all over the Internet. Everyone that wants it already has it. There is obviously no way to undo what has been done. I believe that Valve should turn this source leak problem around and make it into a money making opportunity. I think that Valve should license the game engine, like Dynamix did for the Tribes2 engine (http://www.garagegames.com/pg/product/view.php?id=1). The source is already out there, so why not make money from this problem? No doubt that the people that already have the source will pay to legally have the code if the engine was licensed. I know I would pay to get my hands on this engine. The Torque engine (Tribes2) is licensed for $100 per programmer (non-commercial). A commercial license for the Torque engine is around $10,000. I am sure Valve could raise both of these prices significantly since Source is most likely superior to Torque. What do you guys/gals think of this idea? The source is out there, so I don't see why Valve shouldn't make some serious money from this huge problem. The hackers think they have prevailed....until Valve makes lots of cash as a result of what they did.
