Games of about 10hs from before 2019?

• King of Dragon Pass: Tribe management game/text adventure with illustrations. Felt it was interesting in both mechanics and vibes
• Plants vs Zombies: Addictive comedy-themed tower defense
• Alundra: PS1's Zelda
• Gris: Atmospheric 2D puzzle platformer
• Celeste: Rewarding 2D platformer with nice music
• The Lion's Song: Graphic aventure light on gameplay and heavy on story and atmosphere. 4 chapters about early 20th century Austrian artists and scientists with themes like art, gender, identity, memory, society, etc.
• Orwell: Keeping an Eye on You: You play as a government employee tasked with finding people deemed as terrorists by the gov by scouring their social networks. There's different ways to play it
• Papers, Please: Similar to above but as a border control agent
• The Banner Saga: Tactical RPG bases on viking mythology
• Rebuild: Gangs of Deadville: Management of a group/colony of customizable survivors in a zombie apocalypse. Web game

These are more recent but they should require very low specs:

• Roadwarden: Very well written and immersive text adventure with RPG elements. Low fantasy world, you're assigned as a roadwarden by a far away nation to a dangerous and sparsely populated wildland.
• Landnama: Viking tribes settling Iceland. Plays like a well designed board game in video game form. Real time with pause.
• Citizen Sleeper: Incredible cyberpunk text-heavy adventure with RPG elements and a narrative focused on being humane in a not so humane world with a not quite humane body
