The website Adventure Gamers is publishing a series of articles written by Ben Chandler, the graphic artist behind several games like Technobabylon, Shardlight and two games of the Blackwell series.
Many adventure games, both classic ones and modern ones, are analyzed and cited to explain how the designers used graphics to convey a mood and which techniques were used to achieve specific effects.
Every article is dedicated to a topic and the latest article of the series, published just a few days ago, is about “Other Dimensions”, meaning any kind of different reality that has been used in a story: dreams, fantasies, parallel dimensions and so on. Here is the link:
A Look at Graphics: Other Dimensions
Several popular classics are cited in the article (MI2, Grim Fandango, etc.) and I would like to quote a short paragraph about “Sam & Max Hit the Road”, because I have just cited this game in another thread.
Sam & Max Hit the Road does something slightly similar – here Sam’s foray into the world of virtual reality is represented as a comical, angular vision of wonky shapes that move in odd ways. It feels like the designers were using this to poke a bit of fun at the idea of escapism in games, particularly the simplistic 3D experiences that were possible with the technology at the time. The fact that it shows Sam’s actions back in meatspace adds to the moment, with his movements, when taken out of context, being a bit more fun at the expense of virtual escapism.
I suggest reading the whole series of articles because they are really a good example of an “illustrated guide” to adventure game graphics:
