Japanese solo dev adds Czech localization for the one Czech user who wishlisted his game

Japanese solo developer Eba Game is adding Czech language support to Ball Boy Simulator days before its Steam launch — all because one person from the Czech Republic wishlisted the game.

Eba Game spotted the single Czech wishlist entry and made the call immediately. "One day, when I checked my wishlist, I saw that just one person from the Czech Republic had signed up. I know from the recent World Baseball Championships how much respect the Czech Republic has for baseball and Japan," he wrote on X. "So for the sake of this one baseball fan in the Czech Republic, I implemented Czech language support. Wait for me, my Czech friend." The game's Steam listing notes that AI-generated content was used for some asset textures, background music, development assistance, and promotional materials — which likely explains how last-minute localization is even feasible.

The gesture taps into a genuine cultural moment. At the 2023 World Baseball Classic, the Czech national team — mostly amateurs with day jobs — lost to Japan 2-10 but won over Japanese fans in the process. Czech pitcher Ondrej Satoria, an electrician by trade, struck out Shohei Ohtani, and the underdog team's spirit sparked a wave of affection in Japan that's clearly still running. Ball Boy Simulator itself is not exactly a love letter to the sport — the Steam description frames it as psychological horror based on "the oppression and unreasonable treatment experienced in high school baseball clubs," drawn from the developer's own experiences.

The story has spread quickly, with the wholesome framing of one developer going out of his way for one fan resonating well online. Whether the Czech localization holds up in quality is another question — but the lone Czech wishlist holder is at least getting something.
