If DAVE THE DIVER generated the same gross revenue on the Epic Games Store, MINTROCKET would keep approximately $42,993,847 - that's $6,953,637 more than on Steam.
At this revenue level, Epic's concrete platform fee would be $5,726,434. 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 $34,104,197.
Note: This is a hypothetical comparison. Actual sales volumes differ significantly between platforms, and Steam's larger user base typically drives substantially higher sales.
