Do You Need to Play the Older Brigandine Games?

The short answer

No, and the developers say so outright. From the third producer letter:

Brigandine Abyss has no connections to characters or stories from past titles. One of the defining features of this series is the completely original stories contained in the previous game and the one before that, so I really want to make it clear that you can jump in and enjoy it whether you’re a first-time player or series veteran.

Abyss is set on the continent of Meltitea; Brigandine: The Legend of Runersia was set on Runersia. Different continent, different cast, different war. Nothing in the character list requires prior reading.

Why the series jumped to a new entry

The origin story is unusually well documented, because the producer told it across the letters. Two years after Runersia launched on Switch and PS4, its Steam release sold better than expected — enough to restart internal enthusiasm for a new Brigandine. The producer, then on the promotion team rather than development, began writing a proposal on his own time, read through both the complimentary and the scathing reviews of Runersia, and built the pitch from there.

That detail is worth knowing for one practical reason: Abyss is explicitly a response to Runersia’s reception, not an expansion of it.

What is new if you played Runersia

• Rally. The mechanic that temporarily combines a leader with one of their monsters, granting that monster’s trait, did not exist in previous Brigandine games. It is the single largest change to how a squad plays — see Rally and Support.
• Two modes rather than one. Six scripted Story Mode campaigns plus a Mission Mode where any of the 24 nations can be played toward its own win condition.
• A different creative team. Makoto Yamamoto of the Sengoku Basara series directs; Masayuki Horikawa, who worked on Fire Emblem: Path of Radiance, supervised the strategic combat design; Junko Kawano of the Suikoden series and Niji Hayashi share character design; Rei Kondoh composed.

What is familiar

The core shape is intact: leader units command squads of monsters, a continent is divided between nations, and seasons alternate between organising your forces and invading a neighbour. If you bounced off Runersia’s between-battle layer, that layer is still here, refined rather than removed.

Which entry to buy today

Abyss is the current entry, on Steam, PS5, Nintendo Switch 2 and Xbox Series X|S — see release dates and platforms. Runersia remains available on Switch, PS4 and Steam if you want more after finishing, though nothing in it is required first.

If you are unsure whether the systems are for you, the free demo covers two campaign prologues and includes real battles, which is a better test than any comparison table.
