That's just the tip of the iceberg. Valve offers NO tech support! These 'community' leaders expect the community to help you. IF YOU SCREW UP YOUR REGISTRATION KEY IT'S OVER! Don't expect any help from Valve. They do not respond to tech support requests. Also, cheaters abound! There are many ways to cheat. Valve has nothing to address the issue of cheaters. However, the community has stepped up to make mods to prevent cheaters, but as soon as they do, Valve steps up to undo what the community has done saying that only Valve has the right to provide anti-cheat patches. Some community, eh? Here's a capitalist telling everyone to act like communists, but the capitalist community leader fails to take any responsibility.

SAVE YOUR MONEY AND TIME! Just say no to this unethical business plan. There are other games that don't play games with their 'community', and don't expect the consumer to download countless patches immediately upon opening the box.
