Gadgets 360 says: "The game isn't free of issues but it definitely has some bright spots. We would suggest waiting for the final review, instead of rushing out to pre-order the game now, but we're cautiously optimistic about Anno 2205."
Leon from DJ Podcasts writes "Anno 2205 is a city building, economic game at its heart and this is more than enhanced with the addition of all the DLC packs. Two of them, Wildwater Bay and the Tundra add new sectors for you to control. Wildwater Bay brings back another character from Anno 2070, with the sector project to uncover his buried treasure. This area is known for shipwrecks, which are wonderfully detailed, corroded by time and the salt of the sea. There’s plenty of space for you to use as well, to help build your corporation."
The DLC brings new difficulty mode and other additions.
EB: Anno 2205’s Tundra DLC is apparently now live today, so Ubisoft released a new trailer for it to show off the new region.
I asked a couple people about this game and they say it's good but feels like it's missing something. Said I should wait for the complete edition.
