If Meadow - A Shelter Game generated the same gross revenue on the Epic Games Store, Might and Delight would keep approximately $1,145,216 - that's $329,703 more than on Steam.
At this revenue level, Epic's concrete platform fee would be $19,802. 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 $815,513.
Note: This is a hypothetical comparison. Actual sales volumes differ significantly between platforms, and Steam's larger user base typically drives substantially higher sales.
