Dynamix Catalog

Last updated: May 13, 2026

Overview

The Dynamix catalog is the umbrella for everything produced by Dynamix, Inc. — the Eugene, Oregon developer Sierra acquired in 1990 and operated as its primary internal action/simulation studio until Vivendi closed it in 2001.¹² Across 17 years, Dynamix shipped over 60 games spanning eight distinct franchises and several standalone releases, making it the second-most prolific developer in the extended Sierra catalog after Sierra On-Line itself.

Jeff Tunnell and Damon Slye founded Dynamix in 1984 as Tunnell Software, renaming to Dynamix in 1986. The studio’s pre-Sierra catalog focused on flight and tank simulators (A-10 Tank Killer, Sword of Kadash); after Sierra acquired the studio in 1990, Dynamix expanded dramatically into adventure (Heart of China, Willy Beamish), puzzle (Incredible Machine), sports (Front Page Sports), and mech-combat (Metaltech/Starsiege) categories.³

Dynamix’s design DNA — physics-fidelity simulation paired with cinematic presentation — survived its 2001 closure: ex-Dynamix staff went on to found Papyrus partners, GarageGames (Jeff Tunnell’s post-Sierra studio that produced the Torque engine), and contributed to the founding generation of iRacing.

Because Dynamix produced so many distinct franchises, this page indexes the studio’s output as a catalog rather than a single series. Most Dynamix franchises have their own folder in vault/Games/; see the Sub-Franchises section for cross-links.

Major Sub-Franchises

Metaltech / Starsiege / Tribes (1994–2024)

Starsiege: Tribes (1998) is widely credited with founding the jet-pack-shooter subgenre that influenced Halo, Call of Duty: Modern Warfare’s movement systems, and many subsequent games.⁴

Aces series (1989–1995)

Dynamix’s flight-simulator line, the prestige product before Papyrus’s NASCAR sims joined the Sierra catalog.

Year	Title	Setting
1989	Red Baron	WWI dogfighting (Damon Slye design)
1992	Aces of the Pacific	WWII Pacific theater
1993	Aces Over Europe	WWII European theater
1994	Aces of the Deep	WWII submarine warfare

A-10 Tank Killer (1989–1996)

Dynamix’s first major Sierra-published title.

• 1989 - A-10 Tank Killer
• 1991 - A-10 Tank Killer v1.5
• 1996 - Silent Thunder - A-10 Tank Killer II

Incredible Machine (1992–2011)

The physics-puzzle franchise — one of the most fondly remembered Dynamix products.

Year	Title
1992	The Incredible Machine
1993	The Even More Incredible Machine
1993	Sid & Al’s Incredible Toons
1994	The Incredible Machine 2

2000	Return of the Incredible Machine: Contraptions
2001	Even More Contraptions
2011	The Incredible Machine (2011) (iOS revival)

The franchise was an early example of Dynamix’s “physics + creativity” sandbox idiom — players assemble Rube-Goldberg-style contraptions from a parts inventory to achieve goals. Toons added cartoon physics with The Incredible Toon Machine licensed character. The 2011 mobile revival was released by Jeff Tunnell’s GarageGames-era studio.⁵

Front Page Sports (1991–1999)

Dynamix’s sports-simulation line. Each game shipped with realistic team management plus play-on-field gameplay — a high-fidelity contrast to the era’s arcade sports titles. 14 entries across football, baseball, basketball, golf, and racing.⁶ See Front Page Sports Series (planned) for full coverage.

Dynamix Adventure (1990–1991)

Three highly-regarded adventure games using Dynamix’s proprietary cinematic engine, ahead of their time in animation quality.

• 1991 - Heart of China — Pulp 1930s adventure
• 1991 - The Adventures of Willy Beamish — Comedic kids’ adventure

Pre-Sierra Catalog (1984–1989)

Dynamix self-published or used external publishers before Sierra’s 1990 acquisition.

• 1984 - Sword of Kadash
• 1989 - A-10 Tank Killer — One of the first major Dynamix Sierra-published titles

• 1990 - Stellar 7 — Multiple platforms

Studio History

Founding and pre-Sierra (1984–1990)

Jeff Tunnell and Damon Slye founded Dynamix in 1984 (originally Tunnell Software). Early titles like Stellar 7 established the studio’s identity for technically-advanced action-simulation hybrids. Sierra began publishing Dynamix titles in 1989 (A-10 Tank Killer) before acquiring the studio in 1990.¹

Sierra-acquisition era (1990–1996)

After the 1990 acquisition, Dynamix expanded from ~30 to ~150 staff. The studio shipped its most diverse range of titles in this era: adventure (Bates’s Rise of the Dragon), puzzle (Incredible Machine), sports (Front Page Sports), mech (Metaltech/Starsiege), and flight sim (Aces series). The studio produced one of Sierra’s revenue centerpieces during the company’s high-margin mid-1990s.⁷

Vivendi era and closure (1996–2001)

After Sierra’s 1996 acquisition by CUC, Dynamix continued to produce major releases (Tribes, Starsiege, Cyberstorm 2) but the parent’s increasing cost focus reduced creative latitude. Jeff Tunnell departed in 2000, founding GarageGames with several ex-Dynamix programmers. Vivendi closed Dynamix in 2001, scattering its remaining staff across the industry.⁸

Legacy (2001–present)

• GarageGames (2000-2018, Tunnell’s successor studio) carried forward Dynamix’s “tools for indie developers” ethos through the Torque engine.
• Ex-Dynamix programmers contributed to iRacing (founded by ex-Papyrus’s Dave Kaemmer, with multiple Dynamix-alum hires).
• Prophecy Games’s 2024 Tribes 3: Rivals was developed by an Activision-licensed team continuing the Dynamix design tradition.

Critical Reception Arc

Dynamix titles received consistently strong reviews throughout the Sierra era. Notable peaks:

• Red Baron (1989) — Computer Gaming World “Game of the Year” finalist; widely cited as defining the WWI flight-sim subgenre.
• Aces of the Pacific (1992) — CGW “Simulation of the Year.”
• The Incredible Machine (1992) — Cult-classic puzzle title still cited in modern indie sandbox-puzzle retrospectives.
• Betrayal at Krondor (1993) — CGW “RPG of the Year”; widely considered a masterpiece of licensed-IP game design.
• Starsiege: Tribes (1998) — IGN “Multiplayer Game of the Year”; founded the jet-pack-shooter subgenre.⁹
