HoTD: Overkill opened to similar numbers but isn't showing the legs of HoTD 2&3 - probably because of the price. It's $60 Cdn here, more than MadWorld, Dead Rising and twice the price of Bikini Zombie Slayers or NPC Pikmin so the fact that it's even selling as well as it is is somewhat surprising but I think $40 Cdn would be a more appropriate price and it'll sell easily sell over 1m once the price starts to lower.
As for Sega's 'Mature' titles, that's exactly what I think they are - 'M'ature but not terribly 'core'. They are all pretty accessible games for casual players.
