It's mostly some small balance tweaks, a modifed worldmap, and an overhaul of Christianity, splitting it into the main branches: Catholicism, Protestantism and Orthodoxy.

The worldmap kind of stretches the "realism" definition since it has mythological stuff like Atlantis in addition to some extra historical cities... but it's fun.
