Over at rpgcodex.com we are setting up a SMAC PBEM. If you want to play make an account there and then tell me here so I can add you to our PM on that forum.
SMAC = Sid Meier's Alien Crossfire, it's a really underrated and old style entry in the civ series but it has lots of deep mechanics like elevation, sea level rise, the ability to raise and lower terrain thus incidentally rerouting rivers, psionic combat side by side with mundane, ability to outfit unit chassis with different types of weaponry, army, and gear, and much more.
