Neverwinter Nights

You can make a new character as in you choose class, skills, etc.

You can make your own campaigns (like the main story, but with no splash screen), make your own items, modify the monster''s stats and exp they give.

I think it''s a lot better than typical RPG genres (Diablo 2, Baldur''s Gate, etc)

You should be able to import your own models also.
I have the game and got through the first main story.
I love RPGs, but this one ended up being too much of
a rinse/repeat ordeal in its single player campaign.
I have heard good things about its online aspect though.

It has a complete C style scripting system that allows you to create new weapons and new campaigns, you can script npc and a bunch of other stuff. quite cool if you have time to mess with it.

Finally got my NWN shops to work. It would really be nice to fiqure out how to get a henchmen to join a character though. Also made some easy to kill, violent chickens that give you mass experience. Nice for maxing out the level of your character quickly.

My favorite is the little outpost I made. When you enter the main building a large group of goblins and giants attack the outpost''s main gate.

Ha, cool program. To me it is worth every penny.

When I started playing online... it lagged ALOT, it CRASHED ALOT, and well... I don''t know how it is now
