I liked the idea behind pretty much everything. It's NWN2/2.0, as in MORE of all that DnD goodness. Bugs and glitches happen, and I have full confidence in Duster47, Rasael, and Cubicle(sorry if I missed anyone) to sort things out in time.
They have breathed new life into this server, and all the recent updates from content and areas to bug fixes have been awesome to see. I actually get excited when I have to wait to log in due to updates.
That said, something that really stood out for me was the new melee system. I didn't get to mess around with it in-game, but I've read up on it before. I'm looking forward to when it is ready to go live!
Disguises! Long awaited by many I'm sure. As always, a balance must be found through play, and kinks ironed out, but just seeing it go in is both a happy and frightening thing. hah
New PrC's were all very cool in my opinion. Heirophant and Master Alchemist in particular.
