I've been sticking with the classics this past week:
Currently playing Birth of the Federation with the excellent Balance of Power mod installed. Am also playing a Shimazu campaign in Shogun Total War (and holy crap, I forgot how tough their starting position can be!).
Finally, I've started playing GalCiv 2 again (vanilla version) the last few days. Currently have an Iconian campaign going in a Huge map, Normal difficulty, 9 opponents. I've been fortunate to have the Torians, Altrarians, and Arceans as neighbors, as they all seem to be kindly disposed towards me (despite my complete lack of a military at the moment). The Thalans are less happy about sharing a border with me, but I'm hoping I can still get them to warm up a bit.
