Don't get me wrong, I love the occasional game of manipulating humans (or at least attempting to do so), but I play a lot of other online games, and this plotting element on game spy can be unbearable, as people often behave in a fashion that is not in their best interest there. My personal favorite so far was a game where I settled a plains hill and the guy using rome didn't like it. He didn't say anything until I'd already settled though, and then he did absolutely everything he could to make sure neither of us could win (he sat in my territory and used prats to pillage for 70+ turns on quick), meanwhile my neighbor on the other side rushed/killed someone and I wasn't in shape to stop it. In the end, the roman player had 3 cities around 1000 AD, but damn did he whip a lot of prats and send them to me. It was hard, because there was 1 other competent player in there and he wouldn't work with me (probably realized that he had the game won already).
Clearly, the roman player wasn't playing to win, but just to piss me off. I don't want to see that magnified via tech trades, so I can't say I'm a big fan of TT on game spy...maybe with more people who are at least viable (but most good players don't like BLAZING!!!).
2nd favorite story: Someone build roads to "axe rush" me with 6 axes, passing an AI capitol on the way and hitting me with 6 axes around 500 BC. Yeah...EVERYONE in that game was terrible (The AI he passed up quit due to a failed choke on me)...I won easily after witnessing war skills worse than the AI. Again, however, it'd be much harder if 2 slime balls who failed chokes just vassaled to someone and tech whored because they didn't get their way earlier.
