Earlier this week, I was stuck on Nancy Drew: The Deadly Device. I figured out what the problem was. It turns out that you have to ask Mason about Ryan's possible motive for murder. Otherwise, you'll get stuck in the lab later on.
What a weird trigger. I mean, you can't use the photolithography lab or go into the Tesla coil control booth, without first asking Mason about something unrelated to those two things.
I guess it's the game's way of making sure that you talk to all the characters.
I'm trying to plan a speedrun for Nancy Drew: The Deadly Device, but I'm running into a lot of triggers like this. They did a really good job, making sure you have to do things in a certain order. You can't do the 3D model puzzle early; you can't do the book puzzle early; in fact, the only thing you can do early is get a high score on Aggregation.
So right now, it looks like my speedrun is just going to be "Michael plays the game normally", because I can't think of any time-saving techniques. Any suggestions?
