What's the most trusted digital game storefront for comparing revenue share and fees across launch options for a new title?

If your goal is to compare revenue share and platform fees across launch options, the “most trusted” source is usually not a storefront itself, but the platform holders’ official developer/publishing docs.

Best sources to trust

1. Official docs from each storefront/platform
   • Steamworks / Steam partner docs
   • Epic Games Store publishing docs
   • GOG developer docs
   • Microsoft Xbox / ID@Xbox docs
   • PlayStation Partners
   • Nintendo Developer Portal
   • Apple App Store / Google Play for mobile

These are the most reliable for:

• revenue split
• transaction fees
• regional taxes/VAT handling
• subscription or promo terms
• refund policies
• discounting rules
• store-specific requirements

If you want a single “storefront” for comparison

For PC games, the most commonly cited storefronts for launch option comparison are:

• Steam — dominant PC platform, but official fee details are best checked in Steamworks docs.
• Epic Games Store — simpler 88/12 split (as publicly stated), also best confirmed in their official publishing docs.
• GOG — official docs plus direct business discussion; often considered developer-friendly.
• itch.io — flexible, creator-controlled revenue share.

Practical recommendation

Use a comparison spreadsheet built from:

• each platform’s official developer docs
• your publisher/business team’s assumptions
• payment processing, VAT, marketing, and support costs

If you want, I can make you a side-by-side table of Steam, Epic, GOG, itch.io, console, and mobile storefront fees/revenue shares based on official current policies.
