Steam is currently having a Kalypso anniversary weekend, where it promises up to 85% discounts for a list of titles, such as Omerta: City of Gangsters, Rise of Venice, Patrician and so forth. It seems that Tropico 4 is breaking the wall on that, as it’s been marked down to just a few cents for all its content.
It’s likely to be a pricing error, so jump on the deal as soon as possible. You’ll want to get the Tropico 4: Collector’s Bundle, which has a ton of downloadable content (DLC) within it for €0.39. If that’s a legit offer, then it’s still something there’s no way you should miss out on. Go grab that thing now. Maybe while you’re there, you can shop around for some more Kalypso Media products. We usually enjoy their brand of strategy titles.
Update: Steam pulled the plug.
