There are a few threads on the Panda3D engine and its uses for both TT and Pirates...
But not only do you get the same Design Engine as TT, but much of the Battle Code and how it calculates damage also comes from TT (and a large drawback - as it is Hit Ratio based and not Damage Based - meaning more weaker attacks produce more REP points than less stronger attacks...)
Oh well - as long as your in it for the play then its ok
