Modders
A pack, some files.
Teams, riders, races and routes are files. A content pack changes the peloton, and the rules remain the engine’s.
A pack, some files
Teams, riders, races, routes and suppliers are JSON. The game checks the pack when it loads and refuses invalid content.
Route editor
Open a pack, import a GPX trace: the editor proposes the profile, the climbs, the cobbled sectors and the key points. It writes clean JSON, which reads back unchanged.
Command line
Play a race or a season from the terminal. With the same seed, the same result. The lab command measures the engine against its calibration targets.
Replayable saves
A race save is the log of decisions, replayed on resume. If the content or an engine model has changed, the save is refused with a precise message.
