"These were originally auctioned off in 2011 in a one-off event with one property being sold each month, players at the time could bid an amount to win the property with a finish time of 30 days for the auction, last-minute bids were not possible in this event as any bid below a 12 hour time window reset the bidding time to 12 hours, this was to ensure a true earned winner for the house at the fairest possible price for the time. These properties sold for values between 12 and 23 billion dollars each in the original auctions, the only way to buy one nowadays is to purchase from a player who previously owned it, the most recent purchase was in October 2016 where the Royal Penthouse was sold for an estimated 75 billion dollars, almost double the previous sales price of a unique property.
All of them have the normal house staff except some don't have airstrips, so not all have pilots. All have medical facilities so all can hire doctors, as well as the normal guards/maids/butlers. Eagle Island, Iron Fist Hill, Maidengrave, Presidential Bunker and Silo X17 all have airstrips. Not all have yachts either, only Drakkar Sea Fort and Eagle Island have yachts (although that's only extra happiness) The USS Bloodbath, however, doesn't have a swimming pool and is the only unique property without one of those, which means it lacks the +2% gym gains gained from a pool."
The happiness they give are from 6025 to 7975
