on the DRM, again- Sins of a Solar Empire is
A: The best game I've played in a long time. Maybe ever.
B: Completely DRM-less. You dont even need the activation code or the disk in the drive to play. You use the activation code register the game on Impulse (which is like steam but much better, as it doesnt have to be active to play the games you got through it) and be able to update it. Illegal copy = no updates or patches. Legal copy = you own the game you bought and can do what you want with it, and its fully supported by the devs thereafter.
Thats the way to do it.
All these little tricks that are supposed to make the game harder to crack, or limit resales or loans to friends and what have you, or that you need to be logged on to play and save games or whatever, I have no truck with any of them.
