While there has not been any type of collapse of the indie game field since 2015, there are concerns that the market is far too large for many developers to get noticed. Very few selected indie titles get wide coverage in the media, and are typically referred to as "indie darlings". In some cases, indie darlings are identified through consumer reactions that praise the game, leading to further coverage; examples of such games include "Celeste" and "Untitled Goose Game". However, there are also times where the video game media may see a future title as a success and position it as an indie darling before its release, only to have the game fail to make a strong impression on players, such as in the case of "No Man's Sky" and "Where the Water Tastes Like Wine". Discoverability has become an issue for indie developers as well. With the Steam distribution service allows any developer to offer their game with minimal cost to them, there are thousands of games being added each year, and developers have come to rely heavily on Steam's discovery tools – methods to tailor catalog pages to customers based on past purchases – to help sell their titles. Mobile app stores have had similar problems with large volumes of offers but poor means for discovery by consumers in the late 2010s. Several indie developers have found it critical to have a good public relations campaign across social media and to interact with the press to make sure a game is noticed early on in its development cycle to get interest and maintain that interest through release, which adds to costs of development.
