Great trailer! New elements look nice and the redesigned RF, albeit different, looks undeniably Oddworldian. Good news to hear Raymond Swanland is back
The series always had an unusual stance with regards to technology. Bonewerkz and FeeCo. had Victorian stylings, set against futuristic teleporters and robots (shrink, greeter) for example. Even then though, the futuristic elements fitted aesthetically with the older style, almost like experimental and dangerous prototypes built from salvaged pipes and other materials.
To me, Oddworld never really felt sci-fi. If anything, technological aspects seemed more like the insane machinations of mad scientists than the products of giant corporations- precarious and unnerving. The teleporters felt like they were as likely to malfunction and kill you, as actually work.
The new RF looks like it's moved out of the prototype stage, and uses more completed 'off the shelf' products and equipment. I suppose this makes more sense in-lore given the consumer culture. It still looks old, gritty and grimy, but has an extra veneer of functionality. Perhaps not as dark and deadly to me, but very oppressive and corporate.
Not complaining at all, just commenting on what I feel the differences are

I do personally prefer the darker visuals of the original, but New n Tasty is looking fantastic either way, and very atmospheric.
