Every other RPG of 1987 was about saving the world. This one let you negotiate with the demons.
In September 1987, Atlus released their first game. It was a dark first-person dungeon RPG based on Aya Nishitani's science fiction novel — a story where high school students summon demons through a computer program, and where the player's main tool is not a sword but negotiation. While Dragon Quest and Final Fantasy were building heroic quests in sunlit fantasy kingdoms, Megami Tensei drew on Judeo-Christian mythology, cyberpunk aesthetics, and horror. The demon fusion mechanic — combining two captured demons to produce a stronger one — appeared here in its earliest form. It was a new idea in RPGs: instead of leveling your hero to be stronger, you rearranged the demons you had caught. This logic became the organizing principle of the entire Megami Tensei lineage, from Shin Megami Tensei to Persona, and influenced how Japanese developers thought about enemy design for decades. The composer, Tsukasa Masuko, was credited on the original release as 'Project Satan' — a common industry practice of the era when publishers anonymized their developers. He would go on to score nearly every Megami Tensei game through the late 1990s, his dissonant, unsettling style becoming inseparable from the series. The franchise Atlus built on this first game would eventually become their identity.
About this game
Released in September 1987, Digital Devil Story: Megami Tensei was Atlus's first video game and the origin of a franchise that would eventually produce Shin Megami Tensei, Persona, and Devil Summoner. Based on Aya Nishitani's novel series, it placed the player in a first-person dungeon crawler where demons could be recruited and fused — mechanics that defined a new subgenre and remained central to Japanese RPGs for decades. Tsukasa Masuko's score, credited under the pseudonym 'Project Satan', gave the game an eerie atmosphere far removed from most of its contemporaries.

The Story Behind
Megami Tensei emerged in an era dominated by Dragon Quest and Final Fantasy, charting a darker, more unsettling path. Where those franchises leaned on heroic fantasy, Megami Tensei drew on Judeo-Christian mythology, cyberpunk imagery, and horror — a combination that found a devoted audience and eventually grew into one of Japan's most beloved RPG lineages. The demon fusion system, introduced here in embryonic form, became one of the defining mechanics of the entire genre. Less remembered is that the game was not an original concept but an adaptation of Aya Nishitani’s novel trilogy Digital Devil Story, in which a bullied high-school computer prodigy writes a program to summon demons from the Makai. Atlus built that premise onto the first-person dungeon-crawling skeleton of Wizardry, then added something new for its time: rather than only battling the demons, the player could negotiate with them and recruit them — the seed of the series’ signature negotiation and fusion systems. The overt Judeo-Christian imagery at its core (YHVH, Lucifer) also shaped its fate abroad: wary of religious content under Nintendo’s licensing standards of the era, the earliest Megami Tensei games would remain Japan-only for years.
Tricks & Tales
Tsukasa Masuko was credited as 'Project Satan' on the original release — an industry norm of the era where developers and composers were often anonymised by publishers. He would go on to compose nearly every Megami Tensei game until the late 1990s, making his style inseparable from the franchise's identity. The game's developer, Atlus, had not yet established its own publishing operation and relied on Namco for distribution — the partnership that launched one of Japan's most distinctive RPG studios. The game was not an original Atlus concept — it adapted Aya Nishitani’s 1980s novel trilogy Digital Devil Story, whose premise of a bullied student writing a program to summon demons from the Makai became the story Atlus built around. Its development also brought together a rare parent-and-child pairing: Ginichiro Suzuki and his son Kazunari Suzuki, working alongside Kouji “Cozy” Okada.

Maintenance Tips
The gold-plated edge connectors on Famicom and NES cartridges pick up skin oils and oxidation over decades — a gentle wipe with a cotton swab dampened in 90% or higher isopropyl alcohol, stroking along the length of the pins rather than across them, is the accepted standard. Let the alcohol fully evaporate before reinserting. The old habit of blowing into a cartridge is folklore: the moisture in breath causes slow corrosion of the contacts over time, and any improvement you felt came from the act of re-seating the cart, not from the breath itself. Nintendo eventually updated its own troubleshooting guidance to say explicitly: do not blow into your Game Paks.

What to Watch Out For
Before buying, these are the points worth knowing — from someone who handles original Japanese Digital Devil Story: Megami Tensei copies regularly.
Will this Japanese Famicom cartridge work on a North American Nintendo Entertainment System (NES)?
No, not without an adapter. The Famicom uses a 60-pin edge connector while the NES uses a 72-pin connector with a physically different form factor — the two are incompatible at the cartridge slot level. Third-party adapters exist that bridge the pin difference and allow Famicom cartridges to run in a NES. On a Japanese Famicom, NES cartridges face the same incompatibility in reverse. To play Japanese Famicom software, you need a Japanese Famicom, a Famicom-compatible clone console, or a NES fitted with an appropriate adapter.
How should I clean a Famicom cartridge to ensure reliable play?
Apply 90% or higher isopropyl alcohol to a cotton swab and gently wipe the gold-plated PCB edge contacts on the base of the cartridge. Never blow into the cartridge — breath moisture accelerates contact corrosion over time. If cleaning is needed inside, Famicom cartridges use 3.8mm security game bit screws (not standard Phillips); a security bit screwdriver is required to open the shell without damage. Note that most Famicom boot failures originate in the 60-pin console slot rather than the cartridge itself — cleaning the console slot contacts separately with a contact cleaning tool is often the more effective fix.
Before You Buy
Things worth knowing before you buy Digital Devil Story: Megami Tensei
A short checklist for buying a used Famicom cartridge wisely — useful with any seller, anywhere.
-
Choose a seller who tests it before shipping
A copy that has actually been powered on and checked is a known quantity. An untested one is a gamble you only settle after it arrives.
Look for a seller who states it was function-tested and says what they confirmed. A serious seller can tell you exactly what was checked.
-
Make sure it fits your console
This is a Japanese Famicom cartridge with a 60-pin connector; a North American NES uses a 72-pin slot, so it will not fit directly.
Play it on a matching Japanese console or a region-free system, and confirm the listing states the region.
-
If this title saves your progress, check the battery
Cartridges that save use a small coin-cell battery that fades over decades — a dead one wipes your save without warning.
Ask the seller whether the save function was tested. Replacing the battery is possible, but doing so erases any existing save.
-
Check that the contacts are clean
Dirty edge contacts are the most common cause of startup and sound trouble in cartridges of this age.
Choose a seller who cleans the contacts before shipping. A note that it was tested and cleaned means the basics were handled.
-
Confirm it is genuine, not a reproduction
Sought-after titles are targets for reproduction boards with replacement labels.
Ask for a photo of the circuit board and look for factory markings. Favour a shop with a licensed second-hand dealer permit (古物商) — by law its stock has a traceable origin, your simplest guard against fakes.
-
Read the seller's reviews and return policy
A 100% positive record across thousands of sales is close to a guarantee — packing, communication and problem-solving all work for everyone. A return policy protects you if something is off.
Read the feedback and confirm a clear return window before you buy.
The last step before buying anywhere is knowing what it's worth.
