Primogen - you're right. I would guess that the majority of the fan base are nerds. Who else would stay interested in the game after a play through or two? KotOR is a good game, a great game even - but it's not that
good. However, when combined with the ability to script the game to do virtually anything, it goes from being a great game to a phenomenal game. Scripting in NWscript, or any modding for that matter, doesn't come naturally to non-nerds.
That said, about me:
I'm a nerd.
I work as a software developer for American National Insurance.
Some of my interests are Blender, web design, and ice cream.
