There's something inherent about Neverwinter Nights 2 that makes it more difficult to review. At the basic level, this is not a game you get in the box. Sure, it comes with an excellent module, but you are purchasing the engine, assets, and toolkit, thereby granting you, the player and more importantly the adventurer, access to what may well be an nearly infinite buffet of sessions, both online and off. It's hard to deny the value of a kit of that nature, particular given its wide range of future possibilities. That's also a hard product to sell at the concept level: You're paying for a framework and tools and a sample of what this thing can do in the hands of a professional team of designers.
Based simply on the pack-in module, I can't recommend Neverwinter Nights 2 enough to RPG fans and those who follow the table-top gaming systems. Many other players will want to wait patiently for the mod scene to develop, but unless you're a complete no-RPG kind of guy or still enamored of your MMORPG of the week, you'll want to snag NWN2 eventually.
