About This Game

Irrational Exuberance is an experiment to probe the possibilities of full room-scale VR and the HTC Vive, unfolding organically as you discover and engage with deep space phenomena. Prologue is the first taste of the galactic fantasy, delivering you to a lonely asteroid in deep space, underneath comets and giant stars. Irrational Exuberance has been an audience favorite at Sundance and the Kaleidoscope tour and praised as a defining VR experience by the media for its use of space, sense and setting.

The full release, scheduled for late-2016, will feature dramatic interactions, deeply-immersive moments, and impossible vistas.

Featuring:
  • UNCOMPROMISING DESIGN: Exclusively designed for room-scale VR interaction, Irrational Exuberance is a non-violent, organic experience that offers cinematic moments of space, solace and spectacle.
  • AMPLIFIED SENSES: A highly tuned, evocative spatial audioscape takes audiences to the surreal depths of space, from crumbling meteorites to chiming ephemera to the distant hum of stars.
  • HYPER PRESENT REALITY: Beautiful worlds, mysterious sensations, and nuanced interaction weave together to create a heightened sense and awareness of this alternate reality.
  • COMPREHENSIVE PREVIEW: A short, but impactful experience that foretells the events of the full Irrational Exuberance release.

This has great potential as a unique VR experience. I think part of the fun was going in blind, though. If you haven't watched the trailer, don't. Just download this and play it. You'll figure everything out, and it'll be cool.

A weird little experience, but pretty interesting and worth giving a go. I give it 11 Apollos out of 13, one small step for memes, one giant leap for memekind :^)

Mindblowing short little sci-fi / surreal space experience. Definitely worth the free download and 10 minutes or so of your time.

This is the intro to a bigger experience which I will definitely be watching for. Though from what a gathered at a glance, the full release is going to just be more of the same experience (just different scenes with no story). I would hope they could turn this into some kind of story rather than just a cool art/tech demo.

This could help people with fear of heights and fear of samll spaces (exposure therapy).

It is an awe inspiring experience and I can not wait to see more of it!

Thank you!

Irrational Exuberance: Prologue is pretty cool, but its only about 7 minutes long. There also isn't really a game proper here, either. It is more of an experience. I wouldn't even call it a proof-of-concept yet.

But it is free, and while there is a sea of VR shovelware out there right now, this one isn't terrible.

Ok at first I thought this game was dumb and the graphics sucked, because all you do is stand in a really small cave with floating rocks in it that will break apart if you hit them. So I quit the game and didn't think any more about it. Then I saw on reddit someone said this game is going to be awesome, and someone agreed after they realized you can break the walls of your cave. I was like whaaa????

So i go home and fire it back up. First thing I do is hit the cave wall, just once.

Err. Mah. Gerd.

Mind completely blown. I cannot WAIT until the full game is released now. Freakin EPIC!

Brief but amazing, "Prologue" delights in its abstract nature - and defies classification as it is simultaenously not a game yet engages the user at a blissfully intuitive level. It is an experience that really can only be conveyed by trying it, and is sure to delight anyone who has ever gazed at the stars. I hope it is truely just a prologue, and look forward to seeing more.

I think this is the first game review i have ever written on Steam. I felt compelled. This was truly an amazing experience. I really hope there is enough interest to create a full game/adventure/whateverthisis.

This is...there aren't really words. It's beautiful. Existential. I replayed it a few times, and intend to play it many more until the full version arrives.

The second time I played it I just lied on the floor and felt like I was floating. Absolutely amazing.
This is VR. It transports you to another world.
To anyone that says "resolution" or "SDE" or "it's just like wii motes"...I implore you to try this.
It will change your mind...reminded me of 2001: A Space Odyssey. And that's a huge compliment...

WOW! This is one of those "Yea, VR IS REAL" experiences. I had tremendous fun in the 10 minutes I spent in this demo. I look forward to the full game. Note, VR games should not encourage the player to smash upwards, I have whacked my low-profile overhead light and ceiling many times. I hope HTC starts selling replacement controllers soon! ;)

This doesn't seem like a game so much as an experience... but it is a very pretty, immersive experience. Absolutely check it out!

Irrational Exuberance is the most tantalizing experience on the Vive so far, showcasing the Vives tech (VR+motion controllers) in a fully immersive AAA scifi experience of something completely out of this world. I call it an experience, because its not a game (there are no gamified interactions, no objectives to meet, etc), you simply interact with your environment, and enjoy the scenery. The graphics are clear and stylised which works excellent on the Vives limited screen resolution, but the truly astounding feature is the physics. You can smash rocks, push crystals, etc and everything moves perfectly. Its really simple, but its incredibly wonderous. And its free. And when the full experience/game comes out I will be buying it immediately.

Quick edit: Actually, if I had one criticism its that it only lasts 5 minutes (literally), you get involuntarily teleported into the next reality far too soon. I wish I could pick when to transition, so I could play in each space till I was sated. Buffalo Vision, could you please make it so we need to step into the portal/activate something to continue?

THIS IS AMAZING

I'm a bit of an adrenaline junkie, in my life I rode lots of rollercoasters, went house running, went sky diving... nothing I ever did was as terrifyingly awesome as this short demo, no joke.
I started the game knowing nothing at all about it, didn't even see a picture. I had no idea what's coming up, and boy did it take me by by surprise. It wasn't until the fourth play-through that I could keep my cool.

Like others mentioned, this demo is very well suited as an introduction to VR because the controls are so simple and yet it's such a convincing experience.
