Civ V's systems relocated to an alien planet, with affinity paths that visibly change your units as you commit to one. The alien wildlife adds early pressure Civ never had. It was criticised for feeling like a reskin — the diplomacy is shallow, the victory conditions blur together, and the planet never develops the character Alpha Centauri had.

Turn-based tactics stripped to essentials: unit triangle, terrain bonuses, capture points, and COs whose powers meaningfully change how you play. Readable within one mission. The campaign difficulty spikes sharply in its later maps, and there is no undo — a misread on turn three can cost a map you then replay from the start.

The dual-screen entry: two COs per army with tag powers, plus a much longer campaign than its predecessors. More systems on the board than any other entry. Those systems are also the criticism — tag powers can swing a map decisively, and the balance between COs is looser than in the earlier, tighter games.

The most thematically ambitious 4X ever made: factions built on ideology rather than nationality, terraforming that reshapes the planet, and a unit designer that lets you build exactly what your doctrine implies. The writing is exceptional. The interface is genuinely archaic, and running it on modern hardware usually requires community patches.
