I love the Anno series of games. I love the art style and the game mechanics involved in city building. The combat systems are a bit rough, but I normally turn those off. The real challenge for me in those games are building a stable trade web between multiple islands.
Despite my love for the series, I haven’t and won’t be buying Anno 2070. I want to, I really do, but I think it’s asinine of Ubisoft to include their patented must-be-online-POS-DRM in a single player game that’s available through Steam. Why on earth I want to deal with two layers of DRM? Especially when the one layer that’s not needed and offers zero incentives isn’t even managed properly.
