In this post I will focus on the backgrounds and the technical and artistic aspects which are thoroughly intertwined.
But before we delve into the geeky details, you may want to check out this clip, which I found on an old VHS tape. It is from the Danish TV show "Troldspejlet" (Magic Mirror) on DR's channel 1, and aired in the fall of 1995 when the Hugo PC game had just been completed. It offers a glimpse behind the scenes and a quick overview of the production process. The video is all in Danish but has English subs.
In a game like this, a new image is being assembled from all the different resources up to 60 times per second (depending on the power of the computer). As Hugo changes his position, and the "camera" moves with him, the right portion of the background must be shown on the screen, with all the different characters and objects placed correctly upon it.
