Great recommendations there, each got under my skin. I feel the same about David Lynch films, they connect with something inside me, and lodge permanently in my brain.
I’d put What Remains of Edith Finch, Dear Esther, Talos Principle, Stanley Parable, Metroid Prime and maybe Portal 1+2 in there too - they share an authentically mysterious vibe.
Obra Dinn and Outer Wilds hit me hard, they nailed the atmosphere perfectly. Haven’t actually played DE, was a bit put off by the sheer amount of dialogue, but I need to try it.
Shame the instances list doesn’t include reason for blocking. Looking at the names most seem obvious (and I don’t feel like I’m missing out on those) but there must be some grey areas.
