Went through Megazell's free game list last night and found a few more interesting experiences. I mostly stuck to the 3D adventure games, since a lot of that seemed to give a more unique perspective. But some of these were pretty decent.
Forget Me Not Annie
Forget Me Not Annie is a first person horror puzzle game. Developed in the unreal engine. Take on the role of Annie as she traverses her mind solving puzzles with here friend and ally, Howard the Bear. Use telekinesis and the ability to swap locations with Howard to solve the portal style puzzles.

Judith
Judith is a game you play the game from the first person perspective and it's about control.
Megazell's Comment - While trying to summarize this game to a friend I found this review that took the words right out my mind - "Judith is an interactive story in which you literally cannot help but press on even as you unravel the suspenseful plot bit by bit. I found the experience to be surprisingly deep and haunting. The plot ultimately hints at a back story that you are left to interpret for yourself. I was amazed. I want more games like this."

A Mother's Inferno
It is called ‘A Mother’s Inferno’. Presumably a reference to Dante’s Inferno, it is a first-person perspective passage through a personal hell by a mother who has lost her boy. It is visually and audibly painful, highly shocking and disturbing and packed with symbology it doesn’t waste time explaining. At all of 15 minutes long, it is terror and loss condensed. - Polygon.com

Process
Process - is a game project in the adventure genre; its story takes place in several subway train cars. In 20 minutes a disaster will happen - the train will jump the tracks at full speed. The gameplay takes exactly the time designated before the crash. During this period in grim dimly lit interiors, combining cyberpunk and industrial aesthetics, the player is to figure out the situation, try all possible means of rescue and in the end take a brand new look at the portrayed events. It's a game about predetermination of events and the subjectiveness of perception of the surrounding world.
Truth is, it's hard to position the project as a full-fledged game. "Process" is more of an interactive installation or a small graphic novel. But technologically it's a classic first person adventure, panoramic locations with the capability of free 360 view and discreet movement between the panoramas through a point-and-click interface.
The "Process" project is developed by TrainYard - a small team of independent game developers. Development is done remotely, in free time from main work.

SCP-087 aka The Stairwell
Excuse me while I go jump out of my skin. Like Haversine's SCP-087, EZeddy's experimental horror game is based on that well-loved piece of creepy pasta. Unlike the former, The Stairwell is a little more fleshed out. It features an actual prologue, some additional content and the ability to jump, crouch and flip switches. Much like before, I'm not really willing to spoil this for folks so if you're feeling particularly brave today, why not download the game and give it a shot? Just remember the keep the lights on. - Indiegames.com

Which
A short game where you look for a way to open the door out of the small house.
Please be aware that the game contains violence, blood, and slight gore.

Curious if anyone gets any framerate issues with any of these. Both A Mother's Inferno and Which were fairly stuttery for me. I had no problems playing The Stanley Parable though...which ran like buttah. Could just be my "Cry of Fear-necessary" outdated drivers though, haha. My new(er) video card should be here tomorrow, so it'll be interesting to see what kind of noticeable difference there is moving up from an integrated card...even if it's only a modest step up.
