I just bought the Power Grid expansion pack Northern Europe / United Kingdom & Ireland. If you look at the photo, you will see the label Recharged Version and, at the bottom, you will see the following warning:
The maps and power plant cards of Northern Europe/United Kingdom & Ireland in this expansion can only be played with a copy of Power Grid.
I have Power Grid 2004 from Rio Grande Games. Will I be able to use the extension with my copy of Power Grid , or will I have to buy Power Grid Recharged. It's still shrink-wrapped, so I could return it if necessary.
