The largest entry in the Forza Horizon series at launch, before day-one patches or DLC. The ~12 GB PC/Xbox gap is attributed to PC-specific assets (ray-tracing data, uncapped frame-rate support and upscaling files). Note the PC requirements list 167 GB of free space, higher than the actual download because it accounts for install/patch overhead. An SSD is mandatory on PC. Cross-checked across Pure Xbox, Traxion and Game Rant.
