A Japanese Nintendo gem of holographic arena battles between hand-built mini-robots. The customisation dazzles with its depth, the story mode is unexpectedly well written and the two-player versus crackles. A treasure that begs for a fan translation if you don't read Japanese.

First Japanese entry in a Nintendo franchise the N64 never exported, released in February 1999 and developed by Noise. This cartridge is the founding stone of a series that only reached the West from the GameCube onward, making it the sought-after origin of a customisable-robot battle universe later known outside Japan. Desirability rests on this status as a non-localised matrix and on an NTSC-J box that stayed confidential.
An underrated gem
Building your own miniature robot piece by piece before sending it to duel in holographic arenas: that's the addictive recipe of this Japan-only game. Its depth of customisation surprises, even if the pace takes a while to get going. Tinkering strategists and fans of frantic battles will find an unsuspected playground.
Is Custom Robo still worth playing in 2026?
Custom Robo is a Nintendo game in which you assemble fully customizable miniature robots before pitting them against each other in snappy holographic arenas. The depth of the customization system, blending chassis, weapons and parts with distinct properties, offers remarkable strategic dimension, doubled with a narrative RPG strand. The fast fights reward thinking about the build as much as reflexes. Kept exclusive to Japan, it will appeal to fans of deeply customizable fighting games and mechs, founders of a cult series.
