If Palworld generated the same gross revenue on the Epic Games Store, Pocketpair would keep approximately $212,796,535 - that's $22,454,230 more than on Steam.
At this revenue level, Epic's concrete platform fee would be $28,881,346. Epic charges 0% on the first $1 million in annual per-app revenue and then 12% on the remaining amount. On GOG (30% cut), the developer would earn approximately $169,174,516.
Note: This is a hypothetical comparison. Actual sales volumes differ significantly between platforms, and Steam's larger user base typically drives substantially higher sales.
