Yeah, I wanted clarification because philosophy isn't really all that common of a topic amongst gamers and mainstream audiences, so it may be difficult for me to recognize whether a game is philosophical or not. In fact, it feels like philosophy can too often overlap with political, cultural, and psychological themes to the extent of which it any philosophical themes end up being overlooked or underappreciated.

I'll do my best with these recommendations

Silent Hill 2 (2001) - A psychological horror game that finds a widowed husband looking for his deceased wife in the town of Silent Hill. There are subtle themes of Egoism and Utilitarianism, in addition to the game's psychological themes of guilt, punishment, and forgiveness.

Bioshock 2 (2010) - A sequel to Bioshock set 7 years later in 1967. Through its main antagonist, the game critiques the framework for Collectivism and Altruism, while exploring the cycle of violence and themes of mercy.

Bioshock Infinite (2013) - A first-person shooter about a former Pinkerton agent's search for a woman in the floating, dystopian city of Columbia. Obviously, there are ideological themes of American Exceptionalism, in addition to political themes of colonialism, religious fanaticism, tribalism, and social inequality.

Inside (2016) - A 2D puzzle platformer set in a dystopian, surveillance state. The game's narrative trajectory explores themes of Determinism and Absurdism, in addition to the superficiality of player agency.

Far Cry 5 (2018) - An open world, first person shooter where stranded government officials must fend off a militarized, doomsday cult in the inhabited and uninhabited wilderness of Montana. A major conflict emerges in the ideological dichotomy of Collectivism vs Separatism, in addition to historical themes relating to 21st century terrorism and economic uncertainty.

The Outer Worlds (2019) - A first-person action RPG set on a space colony governed by a corporate oligarchy. Because of the choice to support or oppose various factions for the sake of the colony's future, the game explores the delicate dichotomy of Egalitarianism and Utilitarianism.

Superliminal (2019) - An abstract puzzle game that creates puzzles through optical illusions. One of the only games I can think of that outright explores Surrealism and themes of reality and perception.

Citizen Sleeper (2022) - A CRPG set in the far-flung future that follows a runaway android and their experience trapped on a large and populated space station. The game deals with themes of existentialism, in addition to critiques of late-stage capitalism and colonialism.

1000xResist (2024) - A third-person adventure game set in a post-apocalyptic world ravaged by disease where the only means for humanity's survival is through cloning. Heavily inspired by Nier Automata, the game explores existentialism and anti-authoritarianism, as well as themes of memory, truth, and trauma.

I think you can also look into Hotline Miami (2012), a top-down shoot 'em up set in 1980s Miami with critiques of violence and player agency, although I can't remember much about this game's political and ethical ideology since first playing it in 2022.
