I just want to reassure the cynics among you (Skeeter, I'm looking at you ) that when we say we've started from scratch with the game engine, we really mean it. With the old game engine, the graphics engine part of it was replaced several times, and numerous changes were made to other parts of it in all of the games. As explained in the X-Universe News Q&A section, it served us well for a long time but it had reached the end of the line, and in order for us to be able to do new things we made a fresh start.
