I'm going to use this post to sum up all the tech tree errors, or questionable prerequisites.
1. The Hoplite is available at Pottery instead of Bronze Working like other spear units.
2. The Granary is available with Bronze Working instead of Pottery, which is pretty questionable.
3. The Phoenician Bireme comes available at Bronze Working. No other boats come on this path. All other Ancient boats come with Pottery or Sailing.
4. Monotheism doesn't seem to do anything, and both Polytheism and Monotheism are required advances. Is there something in store for these techs that I haven't noticed?
5. The Elephant Archer and Camel Rider come available at Riding, but they can't possibly be used until Elephants and Camels are discovered with Mounted Combat.
6. Does Ritual Sacrifice do anything?
