On the Sierra Sale banner? That is, the title character from Sierra's "The Caslte of Dr. Brain"? I got excited when I saw that, thinking GOG was going to be selling The Castle of Dr. Brain. Guess not. :(

It's from Shivers.

Thanks for replying. I think you're talking about the banner for the article "Where Adventure Games Grew... the history of Sierra Online". That's indeed the logo from Shivers.

I'm talking about the actual Sale Page where all the Sierra games and prices are listed, https://www.gog.com/promo/20200422_sierra_midweek, and in particular, the cartoon of the scientist dude on the right of the banner with the googly eyes. I notice that same character is in The Incredible Machines game page, so maybe it's indeed a different "scientist". I seem to recall that the Sierra game "The Castle of Dr. Brain" was slightly different than TIM, but don't remember exactly how they differ. Maybe TCoDB had more of a "story" to it?

Anyway, maybe it'll come to GOG some day.
