DESCRIPTIONS
Reprint as-is, no changes needed.
SHORTA baseball game with no game to play: live one player's career from 18 to retirement.
MEDIUMLive one baseball player's life from 18 to retirement — a decision-driven career sim with no game controls, where every formula is shown in-game.
LONGCreate one baseball player and live their career from the draft to retirement. Play as a batter, pitcher, or a rare two-way player. There's nothing to control on the field: you pick the training, manage fatigue and injury risk, and negotiate your contract. Every growth formula, at-bat probability, and injury risk is published inside the game — nothing is hidden.
STORY ANGLES
Each is written to carry a piece on its own — they don't stack.
You never swing and never pitch. You only decide. What's left when you remove reflexes from a sports game?
Growth, at-bat probabilities, injury rolls — all readable from the in-game "How to play & formulas" screen. You are never asked to accept an outcome on faith. Hidden stats are the norm in this genre; this game has none.
A paid "+30 talent points" product used to exist. Talent feeds ability, which feeds career score, which feeds Hall of Fame points, which feed talent — so you could buy your way up the all-time leaderboard. It was rewritten as a purely cosmetic unlock. No paid item buys ability directly anymore.
Every App Store review has a developer reply, and the replies say specifically what changed. One report — a player told he's washed up the same year he won the triple crown — got a wording fix three days later. Version went 1.4.0 to 2.0.0 in three weeks.

No. Every team and player, domestic and overseas, is fictional.
No. Saves stay on the device and are never uploaded. The only network use is serving ads.
No. No purchase buys ability or points directly. Purchases remove ads, add conveniences such as save slots, or unlock cosmetics; two of them (the Elite Prospect start and picking your first team) are shortcuts to options you can also unlock by playing (retiring with an S rank, or Hall of Fame points). Rewarded ads are always optional.
In development. No date or price yet — this page will be updated when there is one.
