One of the reasons I was attracted to buying GCII was the lack of strict DRM, in my opinion, DRM is a completely useless waste of time and money, because no matter what, people will find a way around it. I applaude Stardock for thier policy on how they have tried to avoid piracy of thier software. They havn't done it by treating everyone as a pirate, but by rewarding the people who do pay for thier game.
Not only am I impressed by this, but by the fact this game was so cheap compared to others. I bought the collectors edition version, the case was one of the best I have seen (I'm in the UK so our PC games come in DVD cases, not sure if that's changed in the states), the extras were actually worth it for a change, and it all came to a price LOWER than a regular PC game. The thing that drives people to download games is the stupid prices (especially in the UK, where we pay almost double that of americans...on EVERYTHING, companies seem to think £1=$1).
I admit I have downloaded games, but only as a trial, I don't have alot of money to waste on a crappy game, so I like to try them out first, but when I find a good game I WILL buy it. For instance, I tried out Rome Total War, I really liked it, I bought the Gold edition.
I think what some people say is absoletly true in most cases, when someone downloads a game, they had no intention of buying it, so there was no sale lost. Same goes for films, music, etc.
