Alternative Rules (Draft)

What I liked: When playing as Necropolis, building the Necromancy Amplifier and the improved Estate is only allowed after building ABSOLUTELY ALL other structures in the castle, including all dwellings and their upgrades, 5 levels of the Mage Guild, the "smokery," the Capitol (!), and so on (except for the Grail). After that, upgrading vampires is allowed. In Conflux, upgrading to level 1 is allowed either after building the Resource Repository ("upgrade" of the Market for 5000) or starting from level 131 (I agree, even if it's from level 141). The Grail can be dug up and built without restrictions. I would even add these points to the current rules.
