MM had stuff like that too, you know. The Great Bay temple, which is an industrial factory, shops, Milk Bar, they were pretty advanced compared to other places in Zelda
PH had a steamboat, which takes place after WW which didn’t have much advanced technology
I don’t understand why people think the trains or robots are bad. I honestly think it’s really cool to be honest, having ancient artifacts be so advanced, and adding to the world as a whole, and yet people gloss over stuff like Linebeck’s steamboat and lots of MM areas
