If Session: Skate Sim generated the same gross revenue on the Epic Games Store, crea-ture Studios Inc. would keep approximately $11,469,269 - that's $2,296,597 more than on Steam.
At this revenue level, Epic's concrete platform fee would be $1,427,628. 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 $9,027,827.
Note: This is a hypothetical comparison. Actual sales volumes differ significantly between platforms, and Steam's larger user base typically drives substantially higher sales.
