I was playing a large epic game on Oasis, and somehow despite the fact that noone would trade with me because I was "too advanced" Gandhi was able to get every tech I had and 8 others. Despite being my best friend he wouldn't trade any of them (even the two that all other civs had) because I was too advanced. Also every time I discovered a tech I found he must have reasearched at the same time I did or something . Despite being second (I barely had a score lead over him) he never build a single spaceship part.
