This is, without a doubt, one of the best games I have ever played. The plot line is engaging and fast-paced, the sub-quests are fun, the character development is superior to that of most novels, the graphics are great, the dialogue is better than most of what comes out of Hollywood. This game is addictive. The entire game changes depending upon what choices you make, from the smallest to the largest. You can play through the game over and over without being bored, and you discover little tidbits every time you do so.
It was developed by Troika, probably best known for Arcanum, RPG of the Year recently. This development house is top-notch, refusing to settle for inferior product in any aspect. They really outdid themselves this time. Yes, all their games have bugs... a small price to pay, and most are fixed through patches.
The game changes depending upon which of the seven Clans you choose, and even whether or not you are male or female. You can develop your character into a smooth-talker, and finesse your way past obstacles... or, become stealthy and sneak around them... or, make yourself into a weapon and plow through them.
Thus far, I have played through the game four times and I have not become bored yet. This game is the best of 2004, in my opinion.
I can not recommend it highly enough.
Edited-- Make sure to download the official patch! It fixes some of the minor graphical glitches. Also, there's a TON of fan support for this game. I believe they're up to patch 3.3 now.
