What are games that are either very unique or very obscure, that deserve more players in your opinion? (Bonus points if they are cheap and on sale!) stuff like this :

Sayonara Wild Hearts - Every week someone comes to its subredddit, asks for games that are similar and people try to give something, but we all know nothing is quite the same. This is a one of kind piece of art that might reset you emotionally for the week.
What Remains of Edith Finch - Brought magic to walking sims and made them fun for me.
Herald of Havoc - Ive played a lot of FPSs, DOOMs, Titanfall2, CS, Ultrakill, Turbo Overkill, etc, but the most satisfying shooting ever made for me is inside of Herald of Havoc! big statement, but is true. Developers should play this game before making new FPS. Every thing else in the game is very bare bones, which to me is not a problem, because i don’t care for story or graphics on a fps.
Post void / Hazama Queen - Short w pressing games that pull you into a very weird and strange world, very creative and fun.
