LSD: Dream Emulator

One of the strangest and oddest games to come out of the gaming industry, the game was released for the Playstation 1 in October of 1998 by Osamu Sato, who has also been known for his work on Eastern Mind: Lost Souls of Tong-Nou, a point-and-click game made for Windows computers. Gameplay-wise, the game is mostly based on exploring simulated dreams, which mostly works through a transportation system the game calls "Linking," most of the worlds you traversed through the game range from parks with miniature version of the most famous monuments, to a town filled with colorful and psychedelic faces, each dream mostly lasts for about 10 minutes or shorter. When the dream ends, you are shown a graph that displays how your dream went, there are 4 main directions on this graph, Upper, Downer, Static, Dynamic, each outcome of your previous dreams affects the ones you have, for example, if you had an Upper dream previously, your current dream should be slightly more cheerful with more colors, or if you had a Downer dream previously, your current dream will be filled with more ominous and disturbing themes and darker colors, while Static and Dynamic make more or less NPCs and in-game occurrences appear in future dreams. After you are shown how your dream went on the graph, you are then returned to the game's title screen where you can start your next dream.

Sure, Cho Aniki was weird, but LSD: Dream Emulator is even weirder, I'm not even sure how the programmers were able to design a game like this...
