Despite its label of "Pokemon for adults", the Shin Megami Tensei series actually pre-dates the GameFreak series and first appeared on the Famicom as a Japanese exclusive in 1987. Throughout its existence, the SMT franchise and its numerous spin-offs have maintained a reputation for being quite difficult. It's one that's well-earned, as these apocalyptic visions of the future have tested the might and will of players for over three decades now.

The 5 Best Things About Shin Megami Tensei 5 (& The 5 Worst)

The much-anticipated Shin Megami Tensei 5 is here, and while there's a lot of good, it also has some weaknesses.

Whether it's through the endless horde of demons the player can recruit or a nasty boss, Shin Megami Tensei is one of the industry's most challenging RPG series. Along the way to crafting some of the genre's most taxing experiences, Atlus has become one of the premiere RPG developers and has shown their ability to evolve and fine-tune this wonderful series over the past 35-plus years.

Taking place in an alternate timeline to Shin Megami Tensei 4, Apocalypse was released three years after the fourth mainline entry. Post-apocalyptic Tokyo is overrun with the franchise's signature demons and a twisty-turvy story that pits the player up against some of the franchise's toughest bosses and battles.

Like many games in the series, SMT4: Apocalypse makes use of the Press Turn system in combat. This fabulous system allows players to gain more turns and actions by exploiting the weaknesses of the demons, a deceptively complex system that is easy to understand and increases in complexity over time. SMT games from this era are hard to come by these days on modern platforms, but Apocalypse is still worth checking out for one of the franchise's toughest tests.

Despite the eight-year gap in releases between the fourth entry and Shin Megami Tensei 5, this Switch exclusive maintained the franchise's trademark difficulty and presented a dangerous world to explore and survive. One of the first games announced for Nintendo's console, SMT5 puts players in control of a Japanese high school student who gets transformed into the Nahobino as they explore a post-apocalyptic version of Tokyo called Da'at.

Everything That Changed Between Shin Megami Tensei 4 And 5

The latest Shin Megami Tensei entry has changed a lot from the previous games. Here's everything players can expect to be different.

Da'at is filled to the brim with demons both large and small, with everything from the pint-sized Pixie to the towering Metatron. Demon negotiations also return, with some of these cackling trolls being quite difficult to recruit. Whether they take your money and run or zap your HP, it's always a bit of a gamble and adds some more depth to the world. SMT5 is one of the most challenging RPGs that one can find on the Switch and one of the franchise's toughest to overcome.

4 Shin Megami Tensei: Digital Devil Saga

GameFAQs Difficulty Ranking: 3.69/5

  • Release Date: 2005-04-15
  • Developer: Atlus
  • Platform: PS2

Beginning development under the title New Goddess, Shin Megami Tensei: Digital Devil Saga was Atlus' attempt at broadening the audience of the then-niche franchise. But even with those intentions, Atlus still made sure that Digital Devil Saga was a tough game that pushed players to their limit.

As one of several SMT titles on the PS2, it had to compete with the likes of Nocturne and Devil Summoner, but it was up to the task. Not keen to rest on their laurels, Atlus took Digital Devil Saga out of the apocalyptic setting and centered it on a smaller-scale story about warring factions. This change in setting didn't alter the number of intense boss battles or labyrinthian dungeons, a key part of the SMT series that remained intact here.

Between the release of Nocturne on the PS2 and the eventual launch of Shin Megami Tensei 4 on the Nintendo 3DS, Atlus had become quite busy and was in development on several unrelated titles. But when it finally came time to deliver a new numbered title, they didn't let longtime SMT fans down, as the fourth entry was keen to maintain the same level of intensity the series was known for.

Best M-Rated Nintendo DS Games, Ranked

Few games in the Nintendo DS library were actually rated M, making them a rarity. Here are some of the best mature games that came out for it.

Shin Megami Tensei 4 is easily one of the most difficult RPGs that one can find on the Nintendo 3DS, with a huge roster of classic demons, a few of them with brand-new designs to boot. Press Turn makes a comeback, as well, forcing the player to put their best foot forward in every demon and boss encounter. It feels right at home on the 3DS, as the bite-sized gameplay chunks are a perfect way to survive this harrowing trip through the apocalypse.

Genre(s)

Shin Megami Tensei: Strange Journey was a joint production between Atlus and Lancarse, developers of the Etrian Odyssey series. As a result, Strange Journey does feel a bit different but is still just as brilliant and complex as the rest of the series.

Its focus on a surrealist, almost horror film atmosphere blends perfectly with the nasty demons that players will have to survive. Recruiting those demons becomes a bit tougher in this one, as some of them will join or not based on the alignment system that is determined by player choices. It's an altogether bizarre, but equally fantastic entry that is quite a bit more difficult than most of them.

After releasing several games in the franchise, Atlus was looking to potentially retire the SMT series in the late 1990s. But after several tests of the impressive PlayStation 2 hardware and some push from inside the company, Atlus went to work on what many still consider to be the best entry in the series, as well as its most difficult. Indeed, SMT3 is one of the most outrageously punishing and difficult games on the PS2 and easily the franchise's most challenging game.

10 RPGs Just As Hard As Shin Megami Tensei 3: Nocturne

Fans looking for RPGs as brutally hard to beat as Shin Megami Tensei 3: Nocturne will find these titles to be a perfect fit.

Shin Megami Tensei 3: Nocturne was a bit of a revelation for the series, as it introduced the Press Turn system that would become ingrained into the franchise. This system would dictate a lot of how the games would set up their difficulty in later years. Nocturne is infamous for its difficulty, the way it will kill the player and cost them hours of progress, a reputation that is well-earned. It's SMT's greatest challenge and the recent remaster is a great way to revisit it.
