I'm hoping that I'm not raising an issue that has been disucssed to death on this site...... In my latest game I accepted a nearby neighbour as a vassal around 1600AD after knocking one other neibour into submission and was consequently sitting pretty high on the power chart. In reflection I should not have done this, however the deed was done and I had to live with it. At about the mid 1800's I start to check the victory chart to see what was going on and realised that my vassal had three cities rapidly climbing the cultural chart. I had no chance of getting a win this way, and he was going to win about 20 turns ahead of my spaceship launching. So......I looked at ways I could throw him off. I asked for all of his resources - he gave them to me. He was friendly, so if I asked for money or to change civics etc - he just said no. I could not get out of this situation..... Eventually I had to take the frustrating route of creating a stack of spys - putting all my money into esp and then just kept his city in revolt for 30 turns. I just wanted to blow him out of the water but couldn't. The game was capped of with Issabela winning the space race even though she launched 2 turns after me and according to the the turn before had 0 out of 5 casing loaded. Consequently, I don't know whether or not the Vassal could have won, but it seems as though it was very much possible. I have to say, while I love this game, there is stuff into that make you just want to through your can of coke straight throught the monitor! SORRY WRONG SPOT - ACCIDENT WILL POST IN CORRECT PLACE!
