I was involved with many NWN projects over the years. The most notable, was a modular persistent world called "Ith'Landriel." It was a seemless tropical multi-server world, that, by design, was expandable to accommodate as many players as possible: that is, as many as you have the server power and bandwidth for.
Unfortunately, I had to retire this project around the time of my impending divorce. Shame, really, I still love the place. Ith really does hold a special place in my heart. Now I know how the Creator feels about The Land.... (does that make my ex-wife The Despiser?? You decide!)
Anyways, some of the more notable features of Ith'Landriel were:
-Height. While NWN was technically a 3D game, the engine could really only utilize the X and Y plane, with very little that could be accomplished along the Z plane. As you can see from the pics, Ith was a bit different.
-Edges. NWN has the bad habit of making everything an uncrossable edge. Elevations are all edges, water is an edge, and so forth. Ith was designed to be seemless, elevations could be traversed, and you could walk as far in the water as you wished (that is, until the sharks got ya).
-No grinding. The world was designed with NO GRIND in mind. Players would receive 200xp per day. No need to go out and hunt for it. Left more time for real role-playing.
-Player build towns. Everything, and I do mean EVERYTHING was player-based. Crafting, houses, shops, towns, it was all designed to be player managed. So crafters can open shops and spend their time in town socializing, and adventurers could go out and explore the world. It was a very symbiotic balance between player-types here....
Anyways, enough of that hooplah! Here's a few random screens that I have saved over the years. Anyone who's played the game before can see just how much we accomplished at ith..
Ith'Landriel, my pride and joy.
