EA thought only 2 million people would buy a single-player Dead Space 3

According to Visceral Games' story producer Chuck Beaver, the audience for single-player horror games was big, but not big enough back in 2013.

In a recent interview with YouTuber CaptainBribo, he revealed that a decade ago, interest in such titles seemed to be capped at "around 2 million people." That's a sizable number, he noted, but it added up to  "literally nothing" when taking development costs into account.

That upper limit is important to note, given the franchise Beaver previously worked on. Dead Space 3, now over 10 years old, introduced co-op to the franchise, a controversial move back then given the first two games being largely single-player affairs. 

During the 2010s, a number of triple-A horror franchises such as Resident Evil and FEAR introduced co-op or competitive multiplayer (or both) as a way to draw in payers. Those gambits didn't always take with audiences, with many calling the inclusion a betrayal of those series' roots and core appeal. 

Beaver acknowledged this a core problem with Dead Space 3, saying it lost what players loved about the first two installments. "The gun mechanic, the re-crafting...[we wanted] to expand into other gameplay genres and stuff, and I think all those bits together not only didn’t generate a new audience, they lost the old audience."

The risk Visceral took was calculated, he continued, but hurt by the apparent fact that Visceral "[wasn't] allowed to make a horror game from the beginning. So creative director Ben Wanat and I were like, 'Well what are we making?'"

In the years since Dead Space 3, the tide has turned more towards single-player horror's direction. Capcom's remakes for older Resident Evil games (and new installments like Resident Evil Village) have sold and been
