Game Banshee has posted their review of NWN 2. It's a well-written review. The bottom line is that the game scores 8.7/10.00.
If you're not sure what to take away from my review of Neverwinter Nights 2, then take away this: the engine is fantastic. I've heard people complain about bugs and performance issues (you should definitely check your computer against the minimum system requirements and the supported video cards), but the game ran perfectly on my six-month-old computer, and I didn't have any problems with it. Plus, Neverwinter Nights 2 looks great, and with all of the options for character development, I could see re-playing the campaign multiple times just to try out a few. And if the toolkit is as easy to use as it was before, then no doubt we'll see a ton of user created modules eventually, and so Neverwinter Nights 2 should have an extremely long shelf life.
That being said, I wasn't overly enthusiastic about the included campaign. For me it felt a little basic, and I didn't care much about who lived or died, or if I'd be able to defeat the bad guy at the end. I think there are supposed to be some potential romances with your companions, but I didn't detect any in my game, and while the dialogue was well-written, I think the writers only excelled at humor and barbs, and had trouble adding in themes with any sort of emotional weight. This is subjective, but for me, if I'm going to spend 60 hours playing a campaign, I need characters and situations I can care about, rather than just a couple of people I can laugh with.
But overall, I'd easily recommend the game -- for what will come if not for what's there now. Neverwinter Nights received all sorts of support, both from BioWare and its community of fans, and I'd only expect the same for Neverwinter Nights 2. Obsidian has already released one patch for the game, and I'd be surprised if they're not able to stamp out most of the problems people have reported so far. So if you're a fan of classic, party-based role-playing games, then Neverwinter Nights 2 is definitely a game to buy.
