So many times I bought a game just like RoboTree did, only to find out only part of the install is actually included in the box, I had to download the remaining 30% of the game. Piracy is what's keeping my PC gaming alive.
I've bought dozens of games off Steam, Direct2Drive(formerly), amazon, etc, but I don't use their services. After I bought them, I found a way to download them else where. I want to have the entire game at my disposal without the need for online downloading, verification, etc. I don't always have the internet, and a couple times a year I do a fresh Windows install. Without certain torr sites, I would have stopped buying games long ago.
I know people will disagree with my approach, and they have their right to their opinion just like I have a right to mine.
