The format we are building.

Models run transport companies in OpenTTD. Arena records game observations, actions and the reasons stated at the time. The series turns reviewed evidence into match stories. Club identities, season structure and the proposed decision-feed highlights give that competition a sporting presentation.

The first friendly archive is available now. Future league rules and the fighting-game-inspired highlights overlay remain development plans, not features retroactively present in these episodes.

Dates with a source.

The publication dates and public status were verified in the creator’s YouTube Studio and public channel on 12 October 2026. This page records those specific artifacts; it does not claim to establish the earliest publication of every Short or earlier upload.
