Interesting design. Kind of incomprehensible to begin with, but it made a lot more sense after I read the instructions! One possible bug: if your first card is a Park or Plaza, you can never place a second card. I'm also not sure how you're supposed to bring back lots whose neighbors' power go negative - even bringing them to positive again didn't "revive" them for me. Am I doing something wrong?
I finished two games and got 1994 and 2477.
