Valve has updated the official FAQ for Early Access releases on Steam, now noting that games purchased by consumers within this program "may never be finished." The new warning from Valve in the Steam Early Access, is an answer to the question, "When will these games release?" The answer, according to Valve's update:
"Players should be aware that some developers will be unable to finish their game – for whatever reason." The platform owner also notes that, "It's up to the developer to determine when they are ready to 'release.' Some developers have a concrete deadline in mind, while others will get a better sense as the development of the game progresses. You should be aware that some teams will be unable to 'finish' their game. So you should only buy an Early Access game if you are excited about playing it in its current state."
The update follows several early access games that ultimately didn't deliver what they promised, including the first-person sci-fi post-apocalyptic open-world game Earth: Year 2066, which Valve removed from the service and offered refunds to disgruntled customers to after the game had been labeled "broken" and unfit for sale. The developer, Killing Day Studios, had also been accused of misleading customers with inaccurate claims on the game's Steam product page.
Hammerpoint Interactive's zombie themed MMO The War Z was removed from sale on Steam after the developer was accused of lying on the game's Steam page about the game's content and features. Two months later, the game was again available on Steam, this time with a more accurate product page. In June 2013, The War Z changed its name to Infestation: Survivor Stories following a trademark issue, reportedly to do with Brad Pitt's World War Z film.
