Thanks for the input guys.
V - the dinos from the Turok game are under a 1000 polys each, but the skins are very detailed for the model. Excellent work by the skinner, whoever he is. The Sims 2 girls are a bit higher in polycount, but still under 1500 or so, but the skins are large and detailed if you check them out in the files. I'll release the female base I rigged to the male_alpha_collar in a bit if you or anyone wants to work with it.
Cyber - Tried working with the ant before when doing Eggfu, as well as the other 6 legged meshes out there, and none would work with Blender. The antrider is probably based off the ant I would think.
DM - WAY over my head, but you go! I remember the nature god I think - I'll try to find it and take a look at it. If you can put something together, it could be used in a variety of ways. I'm going to be doing a lot of Civ/ EE ancient soldiers coming up, and it would add some cavalry choices to them. There are some elephant riders as well.
Plus, if it can be rearranged, there are some nice chariots among them - having a human character as a static driver and another one shooting arrows from the back would be very cool.
Here's a screenshot of some of the things I could rig if I had the kfs to work with
