I haven't played Witcher 3, but the way you describe its "beef gates" line up quite a bit with LOZ's design and the aspects of it that BOTW carried over. The entirety of Hyrule Castle is one big beef gate, and there are a lot of other examples of that in the world. The thing where BOTW likely differs from Witcher 3 is that, as a sandbox game, it has more options for creative solutions around these besides brute force and what limited other options an RPG would give you.It’s true that it’s not really pseudo, it’s more like it’s steered. I’m trying to find a prefix that distinguishes between an open world where you can easily go anywhere and an open world where you have to beat Punchout’s Mike Tyson to go somewhere the developers don’t intend for you to go first ... it’s virtually impossible, but technically possible. Perhaps a constrained open world, whether slightly or very? Dunno, but I’m sure you get what I mean.
As for Witcher 3, which parts specifically line up with botw?
By the way, on that TVTropes link, look under the Action Adventure section of the examples for specific examples in the games.
