I want to talk more about the next Nancy Drew game being delayed. The company says they delayed the game because they're switching to a new game engine.
I personally suspect that the game's delay is due to the fact that Her Interactive had to let a number of employees go in May this year. We don't know how many employees are still at the company. The outdated Linked In profile page for the company only lists ten employees.
Another possible reason for the delay? Changing priorities at the company. The first two websites I linked to both mention that the company wants to switch to the mobile games market. My wife says that makes sense; she thinks PC gaming is a dying market, and mobile games are the future. We're told that Her Interactive is working on a new Nancy Drew app, for iOS and Android, to be released in Spring 2015. So maybe Midnight in Salem was delayed, because their major focus is on the upcoming mobile game, not the upcoming PC game.
Her Interactive has tried mobile games before, with limited success. Secret of Shadow Ranch was a text-heavy gamebook. Ghost of Thornton Hall was a port of the PC game. In both cases, the hope was that the games would be super-popular and get followed up by a gamebook based on The Captive Curse and a port of The Silent Spy, respectively. Both those follow-ups were shelved. I didn't think much of it at the time, as this was the fourth attempt to port Nancy Drew games to different gaming systems (DVD, Wii and GBA).
I'm also wondering what will become of the Hardy Boys game. As hinted at in Labyrinth of Lies, Her Interactive got the rights to make a Hardy Boys PC game. If the company is having financial troubles, this game might not live to see the light of day. They made a Hardy Boys game for the DS in 2009, which isn't the greatest game ever, but it's leaps and bounds better than the Nancy Drew DS game made around the same time.
