Video game

A video game, occasionally referred to as a holotape game, is an electronic game that involves interaction with a user interface to generate visual feedback. There are two types of video games in Fallout, holotape games, and VR simulations.

Holotape games
Prior to the Great War, holotape games were a rising medium of entertainment that saw moderate success in public, with holotape games holotapes being sold stand-alone or being included in magazines to entice sales. Dedicated companies and divisions of companies were created to develop holotape games in an attempt to get a foothold in this burgeoning market. holotape games spanned a wide spectrum of genres, including strategic defense, platforms, and text adventures.

Holotape games (and in turn holotape game players) are often looked down upon for being childish and generally a complete waste of valuable time with no redeeming social value. However, even if holotape games are largely useless, they can pass the time and offer a distraction from the reality of a hellish post-apocalyptic wasteland. There are some individuals human and robot alike however, that not only enjoy playing holotape games, but also boast about their skills.

Virtual reality
Virtual reality or VR simulators were a fairly new technology before the Great War and are known to have been in use only in the United States military and in at least one Vault-Tec Vault.

The extent to which the simulators replicate reality is unknown - in some cases, being killed in the simulation results in the person being killed in real life. It is possible this is only an extreme case, as it is a fail safe in Vault 112, and a simulation used to open an armory in the VSS facility. Since, as previously stated, these simulators are known to have no civilian or entertainment applications, the question remains whether they were part of a previous training simulation or other project, possibly involving the development of power armor. Again, due to the limited information available since the bombs fell, this may never be known.

VR simulators

 * A Future-Tec prototype simulation (currently running the active program Tranquility Lane) in Vault 112 (run by Stanislaus Braun as part of the Vault Experiment).
 * Virtual Strategic Solutions's Anchorage Reclamation simulation in the VSS facility (now known as the Outcast outpost).
 * The simulator at the VSS facility is labeled "SIM-U-TEC Chamber 003", suggesting that at least 2 more simulators were built by VSS Inc. Whether these were functional or not is unknown. It is possible that there are simulator rooms behind the doors you see when you go down with the elevator.
 * Flight simulators at Nellis Air Force Base.
 * Nellis Air Force Base near Las Vegas used Virtual Reality simulators to train pilots. After the Boomers settled there they began to use the simulators for the same purpose, hoping to one day recover and refurbish a bomber and put the training to use.
 * VR simulators in the Brotherhood of Steel Hidden Valley bunker.
 * The broken VR in the Stealth Test Area #2 room in the X-13 research facility at Big MT.
 * The Memory Den, where people use simulation pods to access their past memories.

Appearances
Holotape games appear in Fallout, Fallout 4 and Fallout 76. Virtual reality appears in Fallout 3, Fallout: New Vegas.
