Ancient Space is worth a look for those who enjoy linear real time tactical games, but isn't going to be remembered with the same fondness as the games it has been compared to. While the levels look great up close, there's few other redeeming or original qualities.
Galactic Civilizations III is better than Beyond Earth (especially at release), but in this ever improving genre you have to come up with your best shot at launch and, if you want to sell DLC, build on top of that in engaging ways. This genre is one of high replayability and hundred hour games so your product has to challenge last year's fully DLCed 4x games in a substantive way to merit the kind of investment in time, intellectual energy and money that these games require.
Civilization's anything-can-be-traded-however-unlikely diplomacy system was a key element of the game and seems to have been removed and the war and peace system is broken as stands. Hopefully this will all be patched at some point, the way Beyond Earth had a significant patch history, as Rising Tide brings a number of positive changes to the table.
Anno 2205 succeeds where many in the genre have failed in creating an interesting looking world that the player can care about. Experienced players of the city sim and strategy genres won't find anything new here, though, instead finding one of the most rudimentary offerings in terms of mechanics on the market today.
