I've never played Neverwinter Nights, but I've heard a great deal about it. One of the things I've heard often is that the game is more of an editor than an actual game - that the campaign and expansion campaigns are simply there to introduce you to the world and it's possibilities, but that the real NWN experience is to be found in making your own adventures and trying other people's. So my questions are as follows:
Is the editor included in the GOG version (would be surprised if it wasn't)?
How easy is it to make something decent with the editor? Consider this from the standpoint of someone who can make reasonably good maps with the StarCraft II editor.
Is the multiplayer/editor/mapmaking community for Neverwinter Nights still alive in any way? Is there perhaps a GOG community for it?
