The publisher sees a viable mature market on Wii.
Sega recently revealed to GamesIndustry.biz that their strategy of targeting the mature market should be successful over the long-term. While House of the Dead: Overkill didn’t sell millions of copies, it proved profitable for the company according to Gary Dunn of Sega Europe.
"Whilst it had a rather sharp tail at full price, they do bubble away at a lower price point for a long time. You get your money back and a bit on full price, but over the years, if we do the final product return on investment, profits come from the lower price point."
While MadWorld wasn't a commercial success for Sega, Dunn stated that they were happy to take the risk, and that Sega has the budget and resources to invest in publishing and/or developing more mature titles for Wii in the future. The company is currently looking for a new game in which to invest.
