XCOM®: Chimera Squad vs XCOM® 2

Pick XCOM®: Chimera Squad if you want XCOM at street level and in less time. Humans and aliens share one police squad in City-31, and the game trades the war for the peace while staying just as tense. The hook is breach-mode tempo: you breach rooms, the turns interleave with the enemy's, and every agent has a name, a mouth and a grudge. That gives the spinoff its slim story lead, since City-31 faction arcs carry the campaign and the agents' banter carries the rest; it is the only one of the pair tagged Story Rich.

It is also the gentler game. Difficulty sits well below XCOM® 2, and the stakes come from keeping a no-death squad intact rather than from an attrition war against the dice. Build variety is narrower, resting on named-agent synergies instead of class trees and mods, but we think that is where the personalities get room to matter. Campaigns are shorter and tighter, with 21.3 hours against 33.2 for XCOM® 2, and sessions of 30-90 min suit an evening. If you bounced off XCOM® 2's length or its Legend Ironman grind, or you want characters who talk back, we think this is the XCOM to start with.

Pick XCOM® 2 if you want the whole war. It remains the modern squad-tactics benchmark: you lead a guerrilla resistance against alien occupation through procedural missions, and cover, concealment and ability timing give it the deepest combat of the pair by a clear margin. Above the missions sits the full strategic layer, the main reason to choose it over XCOM®: Chimera Squad's district-map operations: a doom-clock Geoscape where routing choices are the only exploration you get.

The soldiers are the second reason. They die for good, you name them and mourn them, and a pulpy resistance arc mostly steps aside to frame that emergent drama; story depth lands a touch below the spinoff's faction arcs, but we think the stories you remember are the ones the game did not write. Build variety is far wider, with class trees, gear and mods multiplying squad identities, and mod support keeps it alive a decade on, which is where the mod-rich replay comes from.

Be ready for the difficulty: Legend Ironman is a war of attrition against RNG and yourself, and sessions of 45 min - 2 hrs across a 33.2-hour campaign ask for real commitment. If you want the harder, longer, more replayable XCOM, we think this is the full campaign pot.
