So I've decided Anno 2070 is going to be my next game but I have a few questions about it. Since I can't get a hard copy and have to download it online, is there any difference in downloading from Ubisoft's website as opposed Steam? If I download from Ubisoft will it still be part of my Steam account? I've not played any of the preceding games, will that put me at a disadvantage with this one? Last of all, is there any reason why I shouldn't get Anno 2070 over Civilization V or Sim City? Any and all thoughts are welcome and appreciated.
