Demo updated (about save data)

Oct 21

Thank you for playing the demo.

Ahead of the full release on October 27, we have updated the save data format.
As a result, saves started before October 21 can no longer be continued. When you open an old save, a notice will appear — choose "Delete this save and start new" to begin a new game right away.

Saves you start from now on can be continued in the full game. On the same PC, they carry over automatically when you launch the full game.

This update also fixes:
- "Back to title" on the old-save notice did not return to the title screen
- "Continue" on the title screen could not be selected even when a save existed

The pre-game screen now shows how long a game takes in each viewing mode (pitch by pitch ~6 min, at-bat by at-bat ~2 min, highlights ~1 min).

We apologize for the inconvenience. The full game is scheduled for release on October 27 at 13:00 JST.

Steam Next Fest: Our 48-Team Baseball GM Demo Is Available!

Oct 16

We are joining Steam Next Fest!

Our baseball general manager game is participating in Steam Next Fest: October 2026 Edition. The free demo is available now.

Festival: October 19–26, 2026, starting and ending at 10:00 AM Pacific Time.

Build the history of your local club

Manage one club in a fictional Japanese baseball league with 48 teams: one in each prefecture, with two in Tokyo. Draft and develop players, build your roster, watch your games, and use the postgame reports to plan your next day.

What is in the demo?

Choose your club and play through the opening exhibition, draft and spring camp, then the first in-game month of the regular season (27 games). Progress can be saved and carried over to the full game on the same PC and Windows user account. The limit is based on in-game progress, not days since installation.

Please note: the game and demo currently support Japanese only.
