NWN 2 I'm really NOT looking forward to, and I absolutely loved the first + expansions.
I've read some interviews where the developers were worried about the strict schedule being forced on them. They actually fear that the NWN 2 release will be similar to Temple of Elemental Evil. If you played ToEE, you know what I'm talking about.
I'm dearly hoping NWN 2 will be solid, but I'm not buying it until it's been reviewed into the ground and the truth has been revealed.
