T5 has technology beyond TL 15, clones, robots, computers, artificial intelligence, QREBS (!), alien senses, Flux. It has a whole series of easy-to-use Makers: GunMaker, VehicleMaker, ArmorMaker, RobotMaker, SophontMaker, ThingMaker. It includes mapping of star systems and worlds; there's ever the MOARN caveat: Map Only As Really Necessary, or referees would spend all their time just making maps of worlds and systems. There's a rationalized section on Psionics, and more, much more.
