I own only 1 of the above 3 games, although I want(ed) to play all 3 of them.
The Best, and only working, RIGHTS MANAGEMENT that you can apply on your games is:
TRUST OF and RESPECT FOR your CUSTOMERS.
If people want to copy your games to their friends, they will find a way, or know someone who does. Is'nt it then better to have the ability to either SPAWN a copy (like with Diablo and Starcraft) that their friends can use, to get them hooked, see the value of the game, and then decide to purcahse it, than to lock down their system with intrusive and disrespectful copy restriction regimes that in some cases may render the entire system inoperable.
The misplaced faith in DRM lockdowns on the PC will lead to only two things:
a) More innocent fans branded as criminals with all the ripples this will send through society

More console gamers as PC owners become more and more jaded
= DRM on PC Games will result in LESS PC Games
Did I subscribe to totalgaming.net because I wanted to buy all the games? No. I subscribed because I saw it as a good idea, I had previous experiences with Stardock (From GalCiv - which I first played in a downloaded version as a demo then later purchased because it was a good game AND it did'nt cripply my system when I installed it) and I do not believe I am unique in this, because Stardock is still alive, so they must be doing something right (And I hope they do even better in the future [always better one must strive.]).
If you build it - they will come, Yes, there will be customers who are to eager to get their FIX right now than to stop and think about what kind of world they are funding with their money.
Do you want to live in a world where you are treated like trash, that you should be gratefull to get a chance play this game, that you shuld be lucky they even bothered to patch the obviously unfinished RC2 build they released as Final that you bought for 69.95$, that restricts and interfeers with your other applications and where you get absolutely NO support and told to f.off if you complain about your DRM nightmare... This is the DRM Future and I'd rather go down fighting than see it come to that. [Which is also why you should become a member of EFF].
