I love psionics in theory but game creators have had a hard time making them work with a prodomitly magic run system. I've always felt that how Paizo treated the sorcerer has really done a good job at scratching my psion itch, especially since they created the word of power system. You make a word of power sorcerer with a focus on words of body, command, Conceal, Fear, flight, Force, Gravity, illusion, power, teleportation and time combined with the aberration or dream touched bloodline and you have a very close approximation.
On the day when they do make the Ultimate psionics, because lets face it they will make a tone of money when they do even if its of the worst quality, I hope they consider making archetypes and alternate class features with a psionic focus instead of creating 5 new classes from scratch. A mind blade magus interest me more then an all new mind blade. Also if they did do this I hope they would include more science fiction elements. an illithid space ship full of gith slaves landing in a city has the beginning of a full scale invasion. would be a blast to play.
