This is an utterly terrible idea.
1. DRM is problematic because it often fails on a legit copy (especially on older games). So those legit users are gonna end up with a game that doesn't work right.
2. The game will get a name for being buggy, having bad controls, etc. and thus nobody will buy it.
3. Many people pirate as a form of demo (especially when a demo is not available), those people will not buy it after seeing how much the game "sucks".
4. Pirates will still get around it. Take mass effect, it delayed pirates a whopping 2 weeks by doing exactly that (the map required to progress to "act 2" so to speak did not work on pirated versions).
if you want to make people buy your game instead of pirating it, guilt trip them into it. (and disassociate yourself from the abusive DRMs).
You know what this type of DRM means? it means legit customers are gonna have to overcome those issues by getting a crack
PS and the whole "crackers don't care and don't notice" angle is BS... crackers LOVE to show up each other by making "PROPER" releases that fix something another cracker missed
PPS just wait until you get the next version of windows and you can't progress past the first 10 minutes of the game on your legit disk because the DRM isn't compatible with your current OS.
