Evaluation
Irrational Exuberance: Prologue is no longer available on Steam — it has no purchase options and cannot be acquired. The game launched on April 5, 2016 as a free prologue experience for HTC Vive, with the store description promising a full release scheduled for late 2016. That full release never materialized. The last developer communication was a performance patch posted on March 17, 2018, in which the developer acknowledged being "away for some time" and expressed intent to post updates and share more about the future of the project. No further communications followed that post. The game has since been removed from the storefront entirely. The promised full "Irrational Exuberance" release was never delivered.

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.
