At the moment: Superliminal and The Long Dark
In the past: Fallout 4, Skyrim, Minecraft, Worms, No Mans Sky
I love games where I can just chill and explore, enjoying some type of light, non stressful gameplay loop. Fallout 4 might be my favorite of all time for this. I couldn’t tel you what the hell the story is about, any of the characters names or the narrative in their missions, but I can tell you where to find a bunch of different rare and unique items as I have explored nearly every inch of the wasteland. On top of collecting them, I have created a museum of sorts to display all those items along with books, armor, weapons and nearly every permutation of power armor the game has to offer.
I rarely even engage in combat and never engage in conversation. I just sneak around, loot everything I can, and bring it back to my base and organize all my haul into separate containers, bins, toolboxes, etc, or put it on display. It’s immensely satisfying and super relaxing.
