If MELTY BLOOD: TYPE LUMINA generated the same gross revenue on the Epic Games Store, FRENCH-BREAD, TYPE-MOON, Lasengle Inc., TAMSOFT CORPORATION, GameLoop Inc. would keep approximately $10,954,536 - that's $2,220,556 more than on Steam.
At this revenue level, Epic's concrete platform fee would be $1,357,437. 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 $8,618,381.
Note: This is a hypothetical comparison. Actual sales volumes differ significantly between platforms, and Steam's larger user base typically drives substantially higher sales.
