Developers like ID, 3D Realms, Epic... etc, that release "when its done" arent normal developers. They are very rich and do not have to rely on money from distributers to fund developement. Like 99 percent of developers dont have this luxury... and thats a big reason why those few companies release better games and are able to provide endless patches...
... if that makes any sense ...
But I think Obsidian did a good job on this title... I just hope NWN2 isnt rushed.
The Infamous Tonberry will return!
