Following the news that Deep Silver has dropped the Steam release of Metro Exodus for an Epic Games Store-exclusive release, many fans were understandably frustrated with the decision and began to review bomb the entire Metro series on Steam.

To combat review bombing, Epic Games founder Tim Sweeney noted the Epic Games Store will soon get an opt-in review system. The store itself is based on the Unreal Engine marketplace, and so too will be the reviews – because in the marketplace user reviews aren’t required either.

“We think this is best because review bombing and other gaming-the-system is a real problem,” Sweeney explained.

To recap, Valve has taken a 30% cut for games offered through Steam for a long time – Epic is offering a 12% cut. Developers get more revenue and many have been dropping a Steam release for an Epic Store one, with various periods of exclusivity.

The Epic Store is still lacking a number of features Steam has, though. Sweeney recently confirmed offline support for the Epic Games launcher is coming sometime earlier this year.
