History
From Strategy Simulations to Action Hits and Hardware Ambitions
Epyx, Inc. was a prominent American video game developer and software publisher that played a pivotal role in the early personal computer gaming era, particularly on platforms like the Commodore 64, Atari 8-bit family, Apple II, and TRS-80. Founded during the dawn of the microcomputer revolution, the company evolved from niche strategy and role-playing games (RPGs) to mass-market action and sports titles, before overextending into hardware and succumbing to the industry crash of the late 1980s. Its legacy includes groundbreaking RPG mechanics, iconic multiplayer sports simulations, and influential peripherals, with assets still occasionally revived in retro compilations.
Founding and Early Years as Automated Simulations (1978–1980)
The company began in late 1978 as Automated Simulations, co-founded by Jim Connelley (a programmer and Dungeons & Dragons enthusiast) and Jon Freeman in Mountain View, California. Operating initially from Connelley's home, it aimed to publish "Computer Games Thinkers Play," emphasizing tactical wargames and simulations inspired by tabletop hobbies.
Their debut title, Starfleet Orion (1978), was a BASIC-programmed space combat game for the Commodore PET, followed by Invasion Orion (1979). Success came with Temple of Apshai (1979), the inaugural Dunjonquest series entry and one of the first computer RPGs. It featured character stats, real-time dungeon crawling, and sold over 20,000 copies on TRS-80 and PET, later ported to Apple II and Atari 8-bit. Expansions like Hellfire Warrior (1980) and spin-offs (Rescue at Rigel, Star Warrior) used a shared BASIC engine.
Introduction of the Epyx Brand and Shift to Action (1981–1983)
As titles like Crush, Crumble and Chomp! (1981) deviated from pure simulations, the company introduced the Epyx brand (a phonetic twist on "epics," after "Epic" was unavailable) for action-oriented games. Internal tensions arose: Freeman departed in 1981 over Connelley's reluctance to upgrade the engine, founding Free Fall Associates with Anne Westfall.
Connelley secured venture capital in 1982, leading to a management overhaul. Michael Katz became CEO and the firm merged with Starpath (makers of the Atari 2600 Supercharger) for assembly-language talent. Connelley left in 1983 to form The Connelley Group, which contracted with Epyx (e.g., Dragonriders of Pern, 1983). The company fully rebranded to Epyx in 1983, discontinuing strategy focus as arcade-style games outsold them. By 1984, Epyx ranked as the 16th-largest microcomputer software firm with $10 million in sales.
A precursor to the eventual shift to action-oriented games, Jumpman (1983) was an externally licensed hit that bridged the post-Connelley era.
Peak Success: Action Games, Sports Series, and Peripherals (1984–1987)
Epyx thrived on the Commodore 64 boom, releasing hits like Pitstop (1983), Pitstop II (1984), and Impossible Mission (1984)— the latter featuring digitized speech and platforming puzzles.
The Games series became iconic:
- Summer Games (1984): Timed for the Los Angeles Olympics, it featured events like pole vaulting and gymnastics.
- Summer Games II (1985), Winter Games (1985), World Games (1986), California Games (1987): Multi-event sports with multiplayer support, selling millions.
Epyx also ventured into licensed properties (G.I. Joe, Barbie, Hot Wheels). In Europe, U.S. Gold distributed and ported games to ZX Spectrum and Amstrad CPC.
Hardware ventures included the Epyx Fast Load cartridge (1984), programmed by Scott Nelson. It accelerated 1541 disk loads by 5x (to ~2,500 bytes/second), added DOS Wedge commands, a machine language monitor, and disk editor. Over 650,000 units sold, boosting compatibility and utility.
Employee perks like beach parties reflected a fun culture, with staff peaking at 145 by 1988.
Hardware Push and Decline (1987–1989)
Seeking growth beyond the fading C64, Epyx hired David Morse as CEO in 1987. Epyx developeding the Handy handheld console (color screen, advanced graphics), but costs soared. As C64 sales declined and the Nintendo Entertainment System dominated, Epyx poured significant capital into Lynx development. In 1989, Epyx sold rights to Atari, who released it as the Atari Lynx. Atari withheld payments amid delays, exacerbating cash flow issues, and leading to filing for Chapter 11 bankruptcy. By the end of 1989, Epyx had laid off most staff, employing less that 20 people.
Post-Bankruptcy and Legacy (1990–Present)
Emerging from bankruptcy in 1990, Epyx focused on Lynx games (Atari publishing) until 1993, when remaining assets sold with only eight employees remaining. Rights transferred to Bridgestone Multimedia Group, then partially to Atari, and later System 3 for re-releases.
In 2006–2007, System 3 ported classics like California Games and Impossible Mission to DS, PSP, and Wii.
At it's peak, Epyx set standards for presentation, animation, and playability, particularly on the Commodore 64 platform. Epyx was also responsible for major technological innovations, including early work on what became the Atari Lynx handheld system. Although the company declined and folded by the early 1990s, its spirit lived on through the designers it inspired, the genres it helped establish, and the fondness with which its games are still remembered.
