This is one of those games that makes me hate the notion of "popularity" sometimes. It is extremely fun, exceptionally well made from a technical standpoint, has a ton of content, and earned glowing reviews from the publications of the time... yet because of how expensive it was to make and its lukewarm popularity, as was common for Looking Glass titles, it never recouped its cost to make and thus the sequels they had planned never materialized. This game SO needs to get a sequel someday.
