Cyan Worlds via PolygonSusana Polo is a senior entertainment writer at Polygon, specializing in pop culture and genre fare, with a primary expertise in comic books. Previously, she founded The Mary Sue.In honor of the 31st anniversary of seminal puzzle adventure game Myst, Cyan Worlds has a new Humble Bundle sale, “Enter the Mysterium.” Through Oct. 2, players can pay $20 and pick up 13 games, which run the gamut from Myst’s earliest 1989 predecessor, to its modern progeny, and every mainline Myst game in the franchise, with part of the proceeds going to Active Minds, a nonprofit dedicated to equipping teens and young adults with the tools to advocate for mental health advocacy and suicide prevention.Enter the Mysterium$20$19290% off$20$20 at HumbleOr, you could pick up any of four smaller, cheaper bundles. But in the opinion of me, Polygon’s foremost Myst-pilled weirdo, here are the titles you should make certain to grab, in order of importance.Myst: Pick your poison! The bundle offers Myst: Masterpiece Edition, which attempts to replicate the experience of playing the original 1993 game; realMyst: Masterpiece Edition, the first attempt to render the game in 3D; and Myst (2021), which supports both 2D, 3D, and VR play.Riven: The Sequel to Myst: This is the intricately cut crown jewel of Cyan’s puzzle games, in its original form. If you get really fed up with it I would also recommend their recent 3D remaster, which improves on perfection (but was released way too recently to be included in a discount bundle just yet).Myst IV: Revelation: Pretty much a direct sequel to Myst. Unequivocally the hardest Myst game, but my personal favorite for its story. It’s got an unskippable Peter Gabriel cutscene. Please, please, please play this game.Myst III: Exile: By no means easy, but still the easiest Myst game. The villain is played by Brad Dourif (The Lord of the Rings) and in one of the “bad endings,” he clubs you to death in first person FMV. If that doesn’t entice you I don’t know what will.Obduction: Not in the Myst setting, but if you play the others first, you’ll be able to call all the plot beats of this one. That said, it’s got a frightfully interesting sphere-based puzzle dynamic, an interesting setup, and gorgeous vistas.Firmament: I haven’t played this one yet. “And you call yourself an expert!” I backed the Kickstarter, OK?! I just haven’t had time! I’ll get to it… sometime after Dragon Age: The Veilguard comes out. I hear it’s worth it, though! And if you’re already picking up the rest, well, why not?But what am I, the Myst-pilled weirdo, going to buy? Well, even though I already own the vast majority of the games in this bundle, there’s still something here for me: Spelunx, Cosmic Osmo and the Worlds Beyond the Mackerel, and The Manhole. Two American dollars will net me three of Cyan co-founders Robyn and Rand Miller’s pre-Myst works, dating back to the unfathomable desktop gaming year of 1988, when Cyan released The Manhole on floppy discs available by mail order (the one in this bundle is a 1995 CD-ROM rerelease).Calling these three games “puzzle games” might seem like a stretch compared to Myst and its successors — I’ve poked around the original Manhole on the Internet Archive, and it’s more like an interactive object. But there’s a sense of humor, silliness, and, above all, play in it. Even just after ten minutes in a browser emulation, it was clear to me that I was looking at a couple of game developers fascinated by the potential of the point-and-click mechanic, and playing in that space as expansively and freely as they could. I could already see the lines running from this strange, Alice In Wonderland-themed object, to a couple of adventure games that were going to bust the genre wide open.Head over to the Humble Bundle, and you can make those connections, too.
