If you spent any part of the 80s hunched over a ZX Spectrum, the name Ultimate Play the Game probably feels like a religious relic. It was the gold standard. That silver-bordered box meant you were about to play something that looked and felt light-years ahead of the competition. But if you look for them today, you won't find a glossy headquarters or a modern Twitter account.
Basically, the answer to who owns Ultimate Play the Game is both simple and a little bit messy.
Right now, the legal entity and all those legendary 8-bit IPs—we’re talking Jetpac, Atic Atac, Sabre Wulf, and Knight Lore—belong to Microsoft. They live under the roof of Xbox Game Studios, specifically within the legendary British developer Rare Ltd.
But how did a small company from Ashby-de-la-Zouch end up in the pockets of a trillion-dollar tech giant in Redmond? It wasn't a straight line. Honestly, it’s a story of disappearing acts, secret handshakes, and a massive 377-million-dollar check.
The Secretive Rise of Ashby Computers and Graphics
Ultimate Play the Game wasn't actually the company's name. It was just a brand. The real company was Ashby Computers and Graphics (ACG), founded in 1982 by brothers Tim and Chris Stamper. Along with Tim’s wife, Carol, and John Lathbury, they ran things with a level of secrecy that would make the CIA blush.
They didn't do interviews. They didn't go to trade shows. They just dropped masterpieces and vanished back into the shadows.

By 1985, the Stampers realized the UK home computer market was a "dead end" compared to what was happening in Japan. They saw the Famicom (the NES) and knew they had to pivot. This is where things get interesting for the "ownership" timeline.
To fund their new venture—a little company called Rare—they decided to sell the Ultimate brand. In 1985, they sold the back catalog and the "Ultimate Play the Game" name to U.S. Gold.
The U.S. Gold Era and the "Fake" Ultimate Games
For a few years, the Ultimate name was basically a zombie. U.S. Gold owned the rights to publish under the label, and they released games like Martianoids and Bubbler.
If you’ve ever played those and thought, "Wait, this doesn't feel like a Stamper game," you're right. They weren't. The Stampers had already checked out to build Rare. Eventually, U.S. Gold stopped using the name, and the rights effectively reverted or were consolidated as the Stampers' new company, Rare, grew into a Nintendo powerhouse.
The $377 Million Microsoft Takeover
Fast forward to the early 2000s. Rare had spent a decade being Nintendo’s golden child. They gave the world Donkey Kong Country, GoldenEye 007, and Banjo-Kazooie. Nintendo owned a 49% stake in the company, but they never pulled the trigger on buying the whole thing.

In 2002, Microsoft stepped in.
They bought the Stampers' 51% stake and Nintendo's 49% stake for a staggering $377 million. This deal included everything Rare had ever touched that they actually owned.
While Nintendo kept the rights to Donkey Kong and Star Fox Adventures (because those were Nintendo’s characters to begin with), Rare—and by extension Microsoft—retained the rights to the entire Ultimate Play the Game library.
That is why, if you boot up a modern Xbox and download Rare Replay, you’ll see that iconic "Ultimate" logo appearing before games like Jetpac Refuelled or the original 1983 Lunar Jetman. Microsoft owns the trademarks. Microsoft owns the code.
Wait, what about the Stampers?
You might wonder if the original founders still have a finger in the pie. Nope.

Tim and Chris Stamper left Rare in 2007. They've since been involved in other ventures, like FortuneFish, but they don't own the "Ultimate" name anymore. It’s a common misconception that the creators of old games keep the rights. In the world of 80s software houses, those rights were usually traded, sold, or swallowed up by bigger fish during the corporate consolidations of the 90s.
Why it matters in 2026
You might think 40-year-old games don't matter, but in the era of digital preservation and retro-remakes, ownership is everything. Microsoft has been surprisingly respectful of the Ultimate legacy.
- Rare Replay: This collection is the primary way to play the Ultimate catalog legally today.
- IP Protection: You’ll notice that when "Spirit" characters or cameos appear in other games, Microsoft's legal team is the one signing the contracts.
- Trademarks: The "Ultimate Play the Game" trademark is still actively maintained by Microsoft to prevent others from using the branding for merchandise or new software.
The "Ultimate" Action Plan for Retro Fans
If you're looking to dive back into this specific history or use these IPs, here is what you need to know:
- Don't expect a standalone revival: Microsoft views Ultimate as part of the "Rare" brand. You won't see a new company called Ultimate Play the Game.
- Play them on Xbox: The Rare Replay collection is the definitive source. It includes 30 games, many of which are the original Ultimate hits.
- Check the Credits: If you find a "new" game using these names on mobile or Steam that isn't published by Xbox Game Studios, it’s likely an unlicensed clone. Microsoft is protective of these specific titles.
- The Emulation Gray Area: While many of these games are available on "abandonware" sites, they aren't actually abandoned. They are owned by one of the largest corporations on earth.
If you want to track the current status of these trademarks or see if any new projects are in the works, keeping an eye on Rare's official social channels is your best bet. They are the keepers of the silver-bordered flame now.
To explore the games yourself, your first step should be checking the Xbox Store for the Rare Replay collection, which frequently goes on sale and remains the most authentic way to experience the Ultimate Play the Game era without a cassette player.
