I'm not a big fan of DRM, but I do see it's importance. So long as I see a seamless integrated approach, I have no problems with DRM. The places I have issues are with games like Crysis Warhead, and what seems to be the above mentioned Goo; having to connect to the internet for the initial activation is, not so much angering, slightly annoying to me. Steam is great for the fact that it has that play anywhere anytime ability, and to top it off you don't need to have internet access at all. But again, with steam, having to set the client to 'Start in Offline Mode' is slightly annoying (come on, there's obviously no internet connection so it would make sense to start in offline mode, then ping out every now and then to see if a connection is later established).
What I would really like to see, just once or twice on a high profile game, is NO type of end user validation. Now, I don't mean don't track the disks, give every disk/copy a specific key-code that the client doesn't have to enter, it's simply written on the .exe (or something), and tell the client that the game will poll with the server, if an internet connection is present, to indicate the .exe code; no personal data will be recorded. Now, I don't mean to use this as a possibility for determining who is sharing their game, but it would be nice to have this type of system to show just how many people do pirate a game. Also, if the game is a pirated game, have it set a couple of flags in the game so that a loading screen or two in the middle of the game says something like "You've been playing this game for a while now. If you would like to support the developers of the game, please visit www.blah.com and submit a payment. You can pay what you think the game is worth." I mean, it might seem like a 'Big Brother' like idea, but I think that most people pirate a game because they either can't afford it, or they just want to try it out and the demo is not enough to get a good feel for the game (problem is, they play it once and will never again touch it). This might just be a win-win situation for everyone. (Oh, and yes I am pulling this idea from Radiohead. I believe they said they made more money with their 'Choose Your Price' album than all of their previous records combined...)
