Relive the magic of Mastertronic games. Dive into the top-selling classics across platforms, quirky histories, and personal favorites in this nostalgia-packed countdown.
A Fresh Journey Through Mastertronic Games
There’s something delightfully unpredictable about peeling back the layers of gaming history, especially when it comes to Mastertronic games. These budget releases shaped entire afternoons and weekends for a generation, and their quirks and triumphs still echo today. Pull up a chair (or a joystick) as we jump into the next five entries in the best-selling Mastertronic lineup.
Feud: Sibling Rivalry and Magical Mayhem

The Pickford brothers made a splash on the Bulldog label with “Feud”, pitting warlock siblings Learic and Leanoric against each other in a frantic hunt for spell ingredients. You don’t just cast spells—you scramble to nab them before your rival does, book in hand.
- ZX Spectrum: 67,184 sold
- Amstrad CPC: 42,195
- Commodore 64: 39,356
- Atari 8-bit: 22,760
- MSX: 19,886
- Amiga: 12,220
- PC: 1,185
On the ZX Spectrum and Amstrad CPC, “Feud” shines brightest thanks to a clever screen refresh trick by Jas C. Brooke, which made gameplay unusually smooth for the era. But here’s the catch—if you stumble onto the Commodore 64 version, be prepared for frustration. Bugs run wild, making the experience nearly unplayable. I learned that the hard way, and can’t recommend it unless you’re collecting oddities.
Surprisingly, the MSX port found eager fans, and the Amiga sales were stronger than you might expect for a budget wizard duel. Seven platforms in total—quite the feat for a low-priced title.
Ninja: Chopping Up the Charts

Who could resist a game called “Ninja” in the ’80s? The team at Sculptured Software launched this beat-’em-up initially for the Commodore 64 and Atari 8-bit, later refining it for a British release under the Entertainment USA lineup.
- Commodore 64: 58,348 sold
- Atari 8-bit: 52,487
- ZX Spectrum: 49,691
- Amstrad CPC: 34,371
- Amiga: 7,983
- Atari ST: 6,162
- PC: 709
The Commodore 64 version even features music from Rob Hubbard—a genuine treat. The Amstrad CPC port, much to my surprise, holds up well and was notably better than my fuzzy memories suggested. Titles with “Ninja” in the name sold themselves back then, so it’s no wonder Mastertronic took a shot at the 16-bit market, too.
While the Amiga and Atari ST numbers weren’t earth-shattering, they’re respectable for the time. Yes, even PC users got a taste, albeit a rather bland one.
Molecule Man: Energy Drain and Isometric Puzzles

“Molecule Man” is an isometric arcade adventure that debuted on the ZX Spectrum. Critics were kind, and the game quickly made its way to other machines:
- ZX Spectrum: 56,216 sold
- Amstrad CPC: 41,124
- Commodore 64: 33,166
- MSX: 31,412
- Commodore 16/Plus/4: 26,716
- Atari 8-bit: 22,059
What I remember most: energy depletes at a breakneck pace. You’re constantly retracing steps, scavenging for supplies to survive—a design choice that’s more exhausting than engaging, honestly. Even the built-in maze editor (a neat feature for its time) can’t always ease the grind.
For some, this game marked the end of their flirtation with isometric adventures. Luckily, the genre’s best was yet to come with later classics. Still, “Molecule Man” is a fascinating, if flawed, specimen from the era.
One Man and His Droid: Herding Robots, Testing Patience

Inspired by the TV show “One Man and His Dog,” Clive Brooker’s adaptation swaps sheep for ramboid robots. The goal: herd them in the right order, but don’t let the simple premise fool you—this is one tough nut to crack.
- ZX Spectrum: 46,921 sold
- Atari 8-bit: 46,383
- Commodore 64: 42,796
- Commodore 16/Plus/4: 39,300
- Amstrad CPC: 37,322
The opening section on some versions is downright punishing—pushing your joystick (and your nerves) to the limit as you battle through a crowd of robots. The Commodore 16/Plus/4 edition avoids this frustration, making it surprisingly playable.
What keeps fans coming back? The Commodore 64’s soundtrack, courtesy of Rob Hubbard, later recycled for the legendary Invade-a-Load tape loader. Atari 8-bit fans nearly kept pace with the Spectrum sales, which was unexpected given the usual trends.
Action Biker: Snack Promotion Turned Cult Classic


“Action Biker” wears its origins on its sleeve—it was an advergame for KP Skips snacks, starring the hapless Colin, whose face adorned the packaging. Sometimes, marketing stunts work out, and this game is proof: solid sales across all three platforms it appeared on.
- Commodore 64: 96,525 sold
- ZX Spectrum: 95,692
- Atari 8-bit: 59,670
On Commodore 64 and Atari 8-bit, you get an isometric motorcycle adventure where collecting upgrades and odd trinkets is key to conquering the final race. Rob Hubbard’s early soundtrack elevates the game on the Commodore 64.
The Spectrum release, though, is a puzzler. Instead of a straightforward port, it became a strange, almost unrecognizable cousin—a baffling creative decision. I found myself scratching my head more than once.
Bonus trivia: some copies shipped in bright yellow cases and cassettes. If you spot one of those, you’ve got a rare piece of cassette history.
Conclusion: The Wonder—and Wobble—of Mastertronic’s Middle Ranks
Peering into Mastertronic’s bestsellers is always a trip down memory lane, but it’s also a reminder that not every risk paid off, and not every port was equal. Yet there’s genuine charm in these eclectic, budget-friendly gems. Which of these classics did you play—or maybe, which one made you want to throw your joystick across the room?
