Finish XCOM 2: War of the Chosen

Firaxis reboots X-COM with 95% shots that miss; the turn-based tactics revival.

Earth lost; run a resistance from a flying base with timed missions.

Base building, research and squads that die in the dark; the 1994 original of the tactics genre.

The underwater sequel, harder than the original in every way.

One city, two alien factions and a real-time mode; the last X-COM the original team made.

Climate, floods and a world congress; the expansion that completed Civ VI.

Nine scenarios from the Peloponnesian War to the Pacific, and the rules changes that made Civ III worth returning to.

Great Generals, vassal states and six warlike scenarios; the first of the two expansions Civ IV is now sold with.
