How Diamond Legend is different
- Every pitch matters. The simulation runs pitch-by-pitch with catcher framing, umpire zones, fielder range, and pitcher fatigue — not a random dice roll.
- One game per day. This is a slow game meant to live in your pocket for years, not a grind.
- Real front-office decisions. Salary caps, luxury tax, TV deals, sponsorships, and stadium economics all affect your roster and your city.
- Your dynasty is yours. Progress saves locally and to the cloud. No competitive matchmaking, no pressure.
