Once someone registers a game with Impulse, it ceases to be a purely physical copy of the game, since it can be downloaded and installed off Impulse at any time.
Once the game is not more register, it cannot "be downloaded and installed off Impulse at any time"... anyway, it is playing with words... maybe somebody will say that today, almost nobody "own" a game but have a license for use it, so "sell or transfer the ownership" is something impossible...
If it is so, Stardock have create the GamersBillOfRights only for try to show them being the good guy and attract new potential customer... somehow like in politic with big promise before the election but once in place, it is the vacuum...
Somehow like their "one price, one world" slogan from the past... actual result is a lot of "US only" game on Impulse... and me being obligate to use Steam for buy these game !!! Speaking of shooting in their own foot !!!
Let's break the rules... GR3mlin60, you can backup you old game and give it to your friend... you can give him a new backup at each update... you friend will not be able to use Impulse or ICO but for LAN game or using Hamachi, it is not a problem ( or maybe, i am not sure that usual sins is compatible with Trinity, seem that Trinity have some mesh difference who don't allow them to play online with usual version )... in fact, the only problem is that these method is called Piracy... so, if you use it, it is at your own risk... and if your friend really love the game, maybe he can buy Trinity like you...
