I agree... I loved NWN2!
Why? (Some people just say they hated or liked it, but please give reasons!)
Party based, with good extended playing system / rules with plenty of fan created mods to make the game replayable etc...
Graphics was ok, and the main game itself was something I enjoyed.
It had a good castle / home base system that was customizable!!!
--> Customizable stronghold is such a great idea. (DAI said it had different strongholds but it was the same every playthrough really) You could build different buildings for different things, and had to look after your own militia / standing army! Was great!
So all the benefits of BG2 but no drawbacks.... Except that the main game story wasn't as good as BG2.
