I personally think that DRM hurts the legitimate consumer of that product more than anything. The pirate will crack any form of DRM within hours. Or sometimes if the game is leaked, will have the cracked version out before it even hits retail shelves. While the people who purchased the game get to suffer with the DRM, the pirates will be on their merry little way playing the DRM free version of the game with no consequences. If a gamer likes a game and the company making the game they will spend money to support that company, regardless of available pirate versions. A pirate obviously doesn't care and wouldn't support the company anyway. For these reasons I believe any DRM beyond a simple CD-Key is worthless, a waste of the game companies money, and has a negative impact on the consumers opinion of said company.
