tried this:
Generate Earth-like planet (10,000km diameter, 24h rotation, 23° axial tilt).
Single supercontinent spanning 40% of surface area, centered on equator.
Remaining 60% is ocean.
Continent features:
- Central desert plateau at 1,500m elevation, approximately 2,000km × 1,500km
- Mountain range along entire eastern continental margin, peaks 4,000-6,000m
- Gradual elevation decrease toward western coast
Looks like it understood only „earth-like“ and 23° axial tilt, the map is fractal.
