Yes, same account, same password, same email, same everything. I am a prinzessin with 10 cities. Often times I log in to my account of a few months ago, as a Viscount, with 5 cities, and in my former alliance, and showing as the host of that alliance.

IF I were not an honest person, that could lead to some rather interesting issues, as I'm sure if I stuck around and tried playing in this warped reality I could probably expel members and wreck utter havoc in that alliance. However, I choose to spend the half hour or so required to get back to my real "reality" (is that an oxymoron?) and get back to where I belong.
