Back in the day (and you can detect its hints in modern adventure games still), we used to deride and laugh at pixel hunting in games. You know how it is - the vital object you need to proceed in your game is a two-pixel blur in a bunch of static background art, and you’d never notice it unless you were lucky or had a guidebook.
Some people apparently liked this process.
Somewhere a developer and a marketing manager banged their heads together trying to figure out how to approach this situation - you couldn’t very well advertise a game as “pixel hunting game”, because market research clearly showed those words started several fights. But then, suddenly, they figured it out.
Now, we’re seeing lots of “hidden object games”, making pixel hunting into an art. Stick your nose to the screen! Search for the missing pixel among others of its kind! Here’s a time limit for you to keep it spicy!
Each to their own, I suppose - hell, I tried out, finished and somewhat enjoyed one particular hidden object hunting game - but it does seem a bit weird in light of the past.
