Oddly enough, the Mule drove me mad. I don’t like this old notion that “we only use 10% of our brain – imagine what we could do if we unlocked the other 90%” that was prevalent in sci fi of the era. So if you gave Foundation and Empire to me in your starter kit, and I reviewed it thus, what would you recommend as a followup knowing that I enjoyed it, but didn’t like the psychic (telepathic) elements?
