If DRAGON BALL XENOVERSE 2 generated the same gross revenue on the Epic Games Store, QLOC, Dimps Corporation would keep approximately $22,371,220 - that's $3,907,112 more than on Steam.
At this revenue level, Epic's concrete platform fee would be $2,914,257. 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 $17,699,834.
Note: This is a hypothetical comparison. Actual sales volumes differ significantly between platforms, and Steam's larger user base typically drives substantially higher sales.
