Game Introduction

Dramatic High School Baseball Simulation! Foster Unique Players!

Game Outline

As a lifelong fan of baseball games, I've crafted a high school baseball simulation that embodies the excitement and drama I've always loved. Our goal is to develop players as unique and compelling as the protagonists in baseball comics.

The game strikes a perfect balance between hitting, defense, and power, ensuring a versatile and engaging experience. When you hit a game-winning home run, the moment is amplified with cool background music and iconic lines that truly bring the game to life.

In this simulation, you step into the shoes of a high school baseball team manager. Your mission is to nurture players with distinct personalities, such as "pitchers who can't control or change their pitches but throw incredible fastballs." Lead your team to victory in the prefectural tournament and the prestigious Koshien tournament, with the ultimate aim of clinching the national championship.

This "dramatic high school baseball simulation" is designed for those who relish strategy and player development, free from any gacha elements.

How to Play

Guide your players' growth by directing their practice sessions. Fielders can focus on improving their meat hitting, power, running ability, defensive skills, and intelligence, while pitchers can work on their fastballs, changeable balls, control, and stamina.

Craft a development plan that aligns with each player's unique personality. Throughout their journey, you'll encounter dramatic episodes such as:

  • A genius pitcher overcoming the yips to finally check first base.
  • A complete beginner in baseball (all abilities rated G) who, through dedicated hitting practice, becomes a regular player by his junior year's summer.

The game's balance has been fine-tuned based on user feedback during development, ensuring there's no single guaranteed path to victory. Your challenge is to find your own strategy and build a team brimming with personality.

Practice progresses monthly, with Koshien qualifiers held in July and September. Winning these qualifiers earns your team a spot in Koshien.

Before each game, set your starting lineup and batting order. During the game, you'll make tactical decisions as the coach, such as calling for bunts, stolen bases, squeeze plays, end runs, or gamble starts.

Tactical instructions can be tailored to the game's situation, such as exploiting gaps between first and second base when runners are on. Animations for batted ball processing and defensive coordination enhance the realism and excitement.

In critical moments, your teammates' enthusiastic cheers and dramatic cut-ins of decisive lines heighten the game's intensity.

Given the high school setting, seniors retire after the summer tournament. We're also planning a "User Koshien" feature (not yet available) where users can compete in tournaments with their teams, preserving data just before the third-year students retire. An official User Koshien tournament is also in the works.

Report a Request or Problem

You can submit requests or report issues at any time by clicking the "Report" button on the left side of the screen. As a solo developer, responses may be delayed, but every piece of feedback and bug report is invaluable for ongoing development.

The game, initially released for Windows, has been continuously improved over the years, responding to over 100 user requests.

Windows Version

The game is also available for Windows. Check it out at https://basebollgame.blogspot.com.
