I just had to clarify this.

As far as I recall, JJ3 uses an old build of the Unreal Tournament engine, a modified Unreal Engine 1. There is no UT99. Just because the game was released in '99 does not make it UT99. The Unreal Tournament's 2003, 2004 (Unreal Engine 2) and the to-be-released 2007 (the Unreal Engine 3) have years in their names because Epic chose to name them that way. The original Unreal Tournament is just that; Unreal Tournament, U.T. No '99'.

Sorry. I see that all the time on other forums and it just bugs me.
