BEWARE OF POTENTIAL SPOILERS IN COMMENTS!
I played The Forgotten City for free via PS+ Extra and it's one of my all-time favorite gaming experiences! I urge anybody who hasn't played it yet but is remotely interested to not look up a goddamn thing about this game beyond this blurb of mine (because spoilers are easy to stumble upon) and play it ASAP!
What is it? It started as a Skyrim mod developed by a lawyer who wanted to make something that's less of a game per se and more of an interactive story that delves into philosophical quandaries like the nature of morality. It's a first person game where you go to an island and wind up in an ancient city of sorts. There's a kind of groundhog day element to it and you have to figure out how to stop that from happening. It's a bit of a mystery, but nearly all of the gameplay is running around and talking to various characters, all of whom have unique personalities. It's like a really robust Fallout New Vegas mission, but without all the combat. You'll probably get through it in 20-40 hours.
Okay, now that that's outta the way, who wants to rant or gush about this little game?
Blackout curtains have been essential for me. Instead of earplugs, I prefer a noisy fan. Circulating the air is good and the constant white noise normalizes hearing stuff, so neighbors or traffic or whatever isn't different enough to wake me.
My wife has a Bluetooth sleep mask, so she can play soothing stuff from headspace or YouTube or Spotify while keeping light out of her eyes. You can find it pretty cheap.
As we enter dry winter months, a small humidifier in the bedroom might also be a good idea.
It also helps to have a routine on how you wind down for bed so that your body and mind can ease into being ready to sleep even if the clock or the sun are telling you otherwise. Maybe do some light reading, wash your face, set out something for the next day (like your outfit), whatever you need and can repeat nightly.
