5 million is quite a high sales target... The slow-selling original Dead Space took 8 months to reach sales of 1,4 million copies. The more action-oriented Dead Space 2 sold faster, shipping 2 million copies in its first week.http://us.gamespot.com/news/dead-space- ... ts-6297125
EA hasn't disclosed the sales figures for DS3 yet. The 28% drop in first week sales was only for the UK market, which is doing worse than some of the others.
Dead Space 3 has been fairly well received critically (Metascore 78%) and some reviewers have praised the game for retaining the suspense/horror element, while at the same time developing the more actioney approach of DS2.http://www.computerandvideogames.com/39 ... isnt-dead/
I've played the demo, read the reviews and it seems that for the most part the game turned out fine. I don't know what Visceral could have done differently. Maybe they should have saved DS3 for next-gen consoles or at least allow more time between the sequels to avoid any franchise fatigue?
Going back to the more strict survival horror approach of the first game probably wouldn't have been a good idea. It just seems too niche as a genre nowadays, if you need to sell millions of copies to make it worthwhile commercially.
