Daydream Software
Their first game was "Safecracker", a point and click adventure game published by DreamCatcher Interactive. The game had a tumultuous production, starting when GT Interactive bought initial publisher Warner Interactive Europe. Daydream Software went public in late 1996. The company's goal was to increase its economic and decision-making freedom, and to secure the ability to select a publisher at the end of each game's development rather than at the beginning. President Jans Phersson-Broburg argued that self-financing Daydream's future games with money from Swedish investors, instead of obtaining "funding linked to specific projects" from publishers, would offer the developer more stability, flexibility and room for growth. For Daydream's public launch, roughly 20 million kr worth of shares, or 45.5% of the company, were offered to investors in Sweden. The initial public offering was a success, and Daydream opened on the Stockholm Stock Exchange's Stockholm Börsinformation (SBI) list in January 1997. Daydream was eventually able to buy back the rights to "Safecracker".
First-person shooter
The earliest two documented first-person shooter video games are "Maze War" and "Spasim." "Maze War" was originally developed in 1973 by Greg Thompson, Steve Colley and Howard Palmer, high-school students in a NASA work-study program trying to develop a program to help visualize fluid dynamics for spacecraft designs. The work became a maze game presented to the player in the first-person, and later included support for a second player and the ability to shoot the other player to win the game. Thompson took the game's code with him to Massachusetts Institute of Technology, where with help from Dave Lebling to create an eight-player version that could be played over ARPANET, computer-run players using artificial intelligence, customizable maps, online scoreboards and a spectator mode. "Spasim" had a documented debut at the University of Illinois in 1974. The game was a rudimentary space flight simulator for up to 32 players, featuring a first-person perspective. Both games were distinct from modern first-person shooters, involving simple tile-based movement where the player could only move from square to square and turn in 90-degree increments. Such games spawned games that used similar visuals to display the player as part of a maze (such as "" in 1979), and were loosely called "rat's eye view" games, since they gave the appears of a rat running through a maze. Another crucial early game that influenced first-person shooters was "Wayout", that while featuring the player trying to escape a maze, it used ray casting to render the maze, simulating visually how each wall segment would be rendered relative to the player's position and facing angle, allowing more freeform movement compared to "Maze War" and "Spasim".
