Yes, of course. My friend wanted to see the game first and then decide to get it or not.
Anyway, it turns out that while you can single play with the fake cd-keys you can not even start a multiplayer game. Because before you start any kind of a multiplayer game it wants you to create an online account. And you can't do that without a proper cd-key.
For the update though, you do
not need a proper key as it's a standalone exe file.
Big thanks again for all your response guys. Cheers!
superfly2000: Updating the game is one thing. Changing the CD-key is another thing.
I don't think that the patch for updating checks the CD-key no...there is only one way to found out though.
To be sure you could just update the game while having the same "old" cd-key on. Update both games I mean....and THEN change the CD-key for the other game.
The thing is....I think the other CD-key needs to be a "proper" CD-key as well. How you will get around with this I don't know really as we are getting close to the borders of legality now...
I am not sure if just cycling the last numbers in the CD-key will help that is...hopefully someone else can answer this....
Personally I don't see the problem with that other friend that you play with just gets his own copy of NWN and that you both get proper CD-keys for online play...then the problem is solved forever....
...it is 10$ we are talking about after all not?....
