Actually, you typed it, but I'll let it slide. (unless you talk outloud when typing) :p
Any case, just to throw in my few cents... if one is expecting NWN to be just as easy to work with as PnP, get a different game. I'd suggest OpenRPG or something, but certainly not NWN. To compare a NWN DMed game with a PnP game is like comparing a, uh, LARP with a PnP game. Various things are the same, most things are completely different.
Improvising with Neverwinter Nights is rather difficult, very difficult. Definately not for the faint of heart. When I host a game, I tend to try and have an entire area ready to toy with. For example, awhile ago, I had the player infiltrate a little town filled with monsters, and before I started that particular session, I had no idea at all what I was going to do with it. I had constructed a little village with all sorts of random things thrown in. 15 minutes before the game was about to start, I qu ickly constructed a little dungeon underneath a building and threw in a few random elements(a large gap, a chest on the other side, a translucent ghost-like minotaur that I could quickly limbo and spawn, a gong here and there) in case of an emergency.
In the end, it was bloody fun. I had a little notepad handy to jot a few things down, and just went with it. Decided that there were two criminal factions whom were trying to get control of the town and just went with it. The dungeon had a use halfway through, and the players got the information that they needed. And to this day, the players still don't completely believe that it was an improvised session.
Of course, Neverwinter Nights tends to work very well with how I tend to plan my games, and used to plan them with Pen and Paper. I simply set up the situations, and let the players have fun with it. As another example, the baron of a small valley had been replaced with a doppleganger and the party had found the original baron. I had no idea on what they were going to do with it. In the last session, with clever use of the invisible spell, the party managed to sneak into the castle and swap the fake baron with the true baron. Was a fun little sneaking mission as a change of pace.
As a few might know, I'm also hosting a little game specifically for Massassians(although a friend o' Wolfy might join soon). As I don't have enough time to start building modules myself, I luckily managed to find a long string of modules to work with, and they've all been built exactly how I like them. Entire plots of land with no fake borders, just a general plotline and various situations for the party to toy with. And ways for me to incorporate the party's histories if I want.
The graphics and tilesets... frankly, I'm not much of a graphic-person to begin with, I suppose, I like what I see. Tilesets may be repetive, but placeables can certainly change the general atmosphere, as well as other different tricks. Give the underdark tileset a skybox, and you have a beautiful mountain area. Give the desert different lightning, and you get an adventure underwater(from what I've heard, see Pirates of the Sword Coast for that). The ease of the tilesets allow me, someone who can hardly model a room to save his life, to create the areas I need to tell a story, that's all I need. And the ease of creating armors, weapons and the like allow me to let the players customise their equipment as well.
(and just to throw in a link,
here is a page that one of the players in my group has created who collects screenshots from my campaign)
The DM Client... well, perhaps difficult to master, but can easily get second nature. I suppose that, coupled with the DMFI wands, it has a learning curve that might seem too steep for some.
Simply put, Neverwinter Nights has downsides, it has limitations and things that might be just plum awful. But frankly, I really don't care all too much about it. It's not Dungeons and Dragons, it's not Pen and Paper, it's Neverwinter Nights. To expect it to be anything else is to be courting dissapointment.
Oh, and hate you for having a different opinion on a computer game? That's certainly an odd view on life.
The answer is maybe.
