Vampires, The Masquerade: Bloodlines. The whole vibe of the setting, the story, the locations, and then when I finally understood what the plot was really about. Masterpiece of a game, couldnt stop thinking about it.

The STALKER series really stuck with me for some reason.It's probably the familiarity of the landscape/atmosphere. Post apoc eastern Europe isn't that much different from normal eastern Europe lol

Barotrauma also stuck with me because of the atmosphere. Amazing game to play solo and feel the weight of the setting, although the bots you play with are a bit iffy and the multiplayer doesn't carry the same feeling of dread and isolation

I’ll never forget loading Myst on my performance 5200 and getting lost

Portal 1.

Something about the ambiance mixed with the puzzles really stuck with me. I replay it almost once a year just to relive it.

Easily RimWorld for me. The stories that play out over time, and how to make productivity more efficient live in my head rent free.
