Marketing research and feedback showed EA that the games were too scary for people even if they enjoyed the "thriller" aspect of it, so, according to EA's marketing boss Laura Miele, they incorporated co-op to somewhat eliminate the fear factor.
EA Games marketing boss Laura Miele told MCV that the single player nature of the titles was largely responsible for the fright factor, hence the publisher's decision to introduce co-op gameplay in Dead Space 3.
But she insisted fans of the series shouldn't be worried that the third game will drop its predecessors' scare tactics in favour of an all-out action approach.
"We were hearing feedback that they love the thriller game, but it was pretty scary, and the obvious next step was that they wanted to play with someone. So we introduced co-op into the game," Miele said.
"The horror of Dead Space is still all there. It's still true to its roots and no less scary, but people felt far more comfortable playing it with someone else than they did doing it on their own.
"Personally, I would rather go to scary movie with my husband rather than sit at home with the lights out watching one on my own. We're looking for that to reach out to consumers that perhaps were not open to Dead Space 1 and 2."
Personally, I think this is really stupid. They're essentially ignoring what I'm presuming made Dead Space 1 (and maybe to a lesser extent Dead Space 2) so compelling for most people who played it. This is the "dumbing down for a mass audience appeal" that we've been seeing happen a lot, and I don't believe that the single player aspect of the game won't suffer because of it.
