But please don't call me Jerry.
At one time, I didn't really like Power Grid so Ted made my piece a Power Grid piece.
1) Can you move souls from an Earth City to another Earth City in Phase 1? (We played it that you cannot)
No. Souls may only move twice; once from hell to earth, and once from earth to heaven.
2) Can you build multiple links in the same turn? (We played that you can)
3) What order do players get to place the New Cities in Heaven? (We played that the auction following the flipping of Hell to Heaven determines the player order)
Almost. The order at the time of flipping the map determines the order of city placement. This means that it's actually the auction _before_ flipping that determines the order. So if it's apparent that there will be few enough cubes left in hell so that it will flip, you should keep that in mind with your bid.
