I've had it for a long time, but I just don't like how often they let people play the mod. Maybe I'll try it later. JC2 is a very good looking game, would be fun MP but I might get annoyed by all the scorpios running around.
That's another thing, you can change your skin with in-game money that you earn from races, or killing people in the free-roam part of the mod. In faction-wars the faction leader can change the skin the entire faction wears. Pretty cool.
