Gemfire done!
The battery in my game is apparently dead, so I couldn't save, and had to beat it all in one sitting. Only the 2nd game I've ever seen that happen to. Pretty good game though, but way too easy. The trading makes it really simple to gain resources, and you can easily get enemies to defect to your side, from the very first turn. And the AI isn't very smart. Still not as boring as some other Koei games, though.
