Since the last update, we've taken the opportunity to do a couple of things with these games. Most of these are fixes, and have been applied to both games (X3: TC + X3: AP); those of you with many playing hours will be pleased to note that one of these addresses the performance and memory issues that can occur with certain missions.
Modders will find a few small improvements in X3AP, and players who use the Russian and Chinese localisations will hopefully be pleased to see text improvements that had been made in X3AP have now been back-ported to X3TC. Also back-ported to X3TC, though currently only in the Windows version, is the controller support from X3AP.
