If Captain Tsubasa: Rise of New Champions generated the same gross revenue on the Epic Games Store, TAMSOFT CORPORATION would keep approximately $5,707,256 - that's $1,262,848 more than on Steam.
At this revenue level, Epic's concrete platform fee would be $641,899. 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 $4,444,408.
Note: This is a hypothetical comparison. Actual sales volumes differ significantly between platforms, and Steam's larger user base typically drives substantially higher sales.
