The Epic Games Store is opening soon to all game developers and it’s launching a massive challenge to the leadership established over the years by Valve with Steam.

It’s doing so by significantly reducing the revenue split fellow developers will face compared to the established norm with Steam. On the Epic Games Store, 88% of revenue will remain in the hands of developers, whereas on Steam traditionally only 70% of revenue went to game studios while Valve kept the other 30%.
