The good parts of Twitcher 3 have nothing to do with the "open world" aspect though. Comparing it to the swill Bethesda makes isn't even appropriate but some people do it anyway.
Buit that's not the issue. I think the problem here is that modern devs tend to think in terms of "mechanics" only and can't see the bigger picture. They see people shoot at animals with arrows in a Bethesda game and they think they have to "copy" that mechanic without understanding why that shit is in there. They don't see that the appeal of Skyrim is the simulationist, LARPing aspect of it. Ubishit games are a primary example of what i'm talking about. Those games are nothing but an assortment of formulae and nothing else. I remember watching my nephew play Far Cry 5 and at no point it felt like he was immersed in the world. It's like he was doing things just to fill up a checkbox.
When you are that contrained by the mechanics you are essentially locked in a linear path whether the game is "open world" or not.
And my theory as to why nobody tried to tap into the same market of Skyrim is that modern gaming companies just don't get what Skyrim is, or where it comes from. Bethesda may be bad at what they do but they are the only ones doing it. That's just damn bizzare, isn't it?
It'd say Red Dead Redemption 2 does a lot of what people like about Bethesda games better than Bethesda games. It's funny because that game is like two totally different philosophies on games smashed together. There's the ultra narrow "do not deviate from the set path" story stuff in RDR2...which sucks. And than there's this ultra simulationist aspect where you can go out and hunt, you can actually track animals without going into tracking "Hunter Vision" mode, when you skin the animal you're going to get this big animal skinning animation with it, and then you've got to put the animal on the back of your horse an haul it to some town or city to get the most out of it; there's other stuff related to this too, like how your inventory works on your horse, needing to dress for the weather, and (kind of) needing to camp if you're staying out for long periods of time. I've got a friend who didn't play video games at all, and it was interesting watching him play that game because the aspect of the game he was interested in was stuff like hunting. Before that one of the few times I'd ever seen him play a video game was years before when I went to the college he was going to and him and his roommate were fucking around with Far Cry 2.
But then Rockstar games are even bigger Skyrim, so they have no reason to even think about going after what Betheada does unless someone their just really wishes to do something like a fantasy or sci-fi game.
Funnily I'd also say Bethesda doesn't even see the appeal of their own games. I mean, I think Fallout 76 kind of made that really clear. But even beyond that, they've never really designed one of their games around what people like about them. The appeal is much the same as GTA3, (and it's probably little surprised Elder Scrolls only really catches on post GTA3 with Morrowind) it's the sandbox, it's going anywhere and doing anything, and seeing how the world reacts to that. Unlike Rockstar games however nobody really gives a shit about the story in Bethesda games, it's why for almost 20 years now when people talk about Elder Scrolls they talk about the side quest being better than the main quest. So why even have a main quest? Why not just present a world for you to fuck around in, factions and systems for you to bounce off of, and that basically be it. Design Elder Scrolls in a way to where the side activities people like most, the main things people like, are actually the main driving force behind someone's playthrough. Like I bet the audience would be more into an Elder Scrolls where, once you're out of prison, if you wanted to do something like join a Gladiatorial circuit, you could just do that and travel around from city to city, rising in the ranks, making money, build a house, and start your own gladiatorial stable with your winnings if you wish...or just fight endless until you're dead. You could have a whole game related to nothing but fighting in arenas if you want, but it's not some little side mission, it could just be your whole game if that's what you wanted it to be and someone else that wanted to do something else could have a totally different experience. The smart way to design Elder Scrolls to me would be to make it so the shit people LARP doesn't have to be some weird fucking LARPing thing because the mechanics actually facilitate those people that want to play at being a merchant or whatever.
