|Classic adventure style game that follows Robert Foster on a journey through a cyberpunk-esque metropolis. Requires ScummVM to be played, or you can download it from GoG.com.

|Ben There, Dan That!||Windows||Ben There, Dan That! and its sequel, Time Gentlemen, Please! are two hilarious and silly indie adventures with MS Paint graphics filled with meta humor humour and references to old LucasArts games. Plays just like Sam & Max Hit the Road and obviously took a lot of inspiration from it. You can get both at once for five bucks on Steam or just download Ben There, Dan That! for free.||Link|
|Chzo Mythos||Windows||Before he became "Internet Famous" for his witty video game reviews, Ben "Yahtzee" Croshaw actually made some games himself.

|Photopia||Windows||Arguably one of the most introspective, haunting interactive fiction games ever created. The story revolves around the life and development of a precocious twelve-year-old girl. However, you never play as her. Instead, you play as several different characters who care for her in different ways.
Along with these perspective shifts, you're also playing through vivid, dreamlike fantasy sequences. There's a common, but subtle underlying theme that is made clear as the game progresses, and one of the last scenes is open to interpretation.
|Slouching Towards Bedlam||Z-Machine||In a dystopian Victorian Steampunk setting, in an alternate timeline, you play as the new head of the local insane asylum. When the game starts out, you're listening to a recording by your predecessor, who rambles about why he committed suicide.
This sparks a chain of events that lead you to explore the asylum and the surrounding city and discover the big secret behind everything, at which point you are absolutely, completely free to choose how to respond, with almost no prompting whatsoever aside from the in-game hints system. The writing is heavily atmospheric. This award-winning work of interactive fiction features five different endings and highly advanced NPCs.

|Spider and Web||Z-Machine||You're a highly trained spy with a wide variety of high-tech gadgetry, and you've been taken captive by your enemies and are being forced against your will to re-live the last hour of your intrusion into their secret compound.
This game has quite a few traditional puzzles, but most of them focus entirely on perspective, on the relationship between the player and the protagonist, and require plenty of lateral thinking to solve. You're also given a wide variety of choices on how to respond to your captors, and the dialogue is rather interesting.
|Stargate Adventures||Windows||A Point-and-Click adventure game where you play as Jack 'O Neall; Takes place between Seasons 8 and 9.||Link|
|Twisty's Asylum Escapades||Windows||Twisty's Asylum Escapades is a dark, 3D, single player, action adventure video game and is the premier gaming project by the masterminds at Twisted Jenius.

|Which||Windows||A short game where you look for a way to open the door out of the small house. Lacks any sort of options and the 'low' quality version is still pretty high so be sure your PC is good enough.||Link|
|White Chamber, The||Windows||You wake up on a ship in space, encounter some very horrifying scenes (despite the cartoonish art direction), and slowly piece together what the hell was going on (it wasn't pretty). This is one you can finish in a couple of hours, but has received very high praise from critics for its clever puzzles, chilling atmosphere, and terrific story.||Link|
|Yume Nikki||Windows||Wander around a little girl's dreams (most of which are extremely disturbing) while collecting abilities, most of which don't do squat. The gameplay is mainly about exploration, as you are not given any specific goal nor given any clue about where to go, and the places available can sometimes be very large. The game heavily relies on atmosphere. Definitely an interesting experience, nonetheless, give it a try. This game has its own chan.
Has several fangames and fan-sequels in the same vein, some linked here:
