One of the things I liked about Oddworld was the fact that they used Machine guns as opposed to Laser guns. I loved how alien and Sci-fi it was, yet it lacked the slick, Star Wars style Sci-Fi that everyone was used to.
When you play Stranger's Wrath, you see that their technology is quite limited in comparison to the Abe games, and is almost as limited as our technology was in late 19th Century. And Stranger's Wrath doesn't take place that much further away from the other three games.
The technology is reletive to how much they need it in a specific area of Oddworld. For example, in the Wild west, it doesn't look like the Clakkerz need technology in their every day life or their jobs, so they can get along fine and dandy without it.
But in order to rake in as much Moolah as possible, the Glukkons need to use lots of technology in order to communicate with other parts of Oddworld, speed up production of products with machines and to make their lives easier.
