In site news, you'll notice that the site name has changed again, this time to The Adventuress. I've been adding non-LucasArts inspired companies to the site, so I decided it was time for a change in scope. I enjoy adventures in general, and not just LucasArts adventures, so I thought this was a good change. :)
