Ok I really want to find this game online and download it. Its a free RTS that is single player and multiplayer. Its really an RTS but with a puzzle element. What makes it stand out is that the only way to move around the map (which is in the sky) is to build pathways. Along those pathways you can build towers and stuff. I know the most important character was the priest and if you captured the oppents priest in multiplayer, you could sacrifice him to get new technology. This is an older game for the PC. If anyone has any ideas please post.
