It's never really mattered to me, and it's also kind of misleading because the size of a world should really be dependent on the method of travel. For instance, the world in Red Dead Redemption 1 feels much larger to me than the world in GTAV even though GTAV is a larger world, because in one, you can cross from one corner to the map in seconds in an airplane, and in the other, it takes ~10minutes (or more) at full gallop to cross. Also the layout of the map makes a major difference. RDR so cleverly used the "path" mechanic and the map design made it so that you'd have ot realistically ride out long distances just to go to a place that was relatively near by. Think about riding from the top of that cliff in Hennigan's Stead down to Armadillo, which is a short ride, but because of the design of cliffs and a winding path to get down, it takes much longer to go a much shorter distance. In GTAV, you could take a mountain dirt bike off the edge and be at the bottom riding along in mere seconds.
Ah, Resetera. You never fail to miss, entirely, the point of a thread.
Like many others in here, I don't personally care how big a world is, except in the odd occasion where they do bigger worlds better than other developers do smaller worlds (The Witcher 3 vs. Skyrim, for instance), BUT, this is still very much a selling point used in marketing. Especially once you consider preview pieces by gaming sites, which are just long-form ads. How long will that take to go away? Probably never. I think it will always be a selling point for open world games.
I think I recall AC Odyssey being touted as having a bigger world than Origins, and my initial reaction being "But Origins was too big to begin with." as much as I loved the game. If I was fifteen and played Origins obsessively, then hearing that Odyssey was bigger and had more stuff in it would be a HUGE bonus. I remember being in high school when the PS2-era GTA games were coming out and being so fucking stoked for San Andreas because instead of one city, it as THREE and then some.
I imagine that 15-22 demo still feels that way.
I agree with you in Ubi open world games because I don't think they utilize their open worlds well. Their maps are so cookie-cutter to me where being in one town in Origins feels almost no different than being in another town in Origins to me. The people are doing the same thing, they're working the same way, are probably the same character models, and aside from noteworthy structures like, say, one might have some unique temple or something, the areas around them are nearly all the same.
I don't agree with Rockstar open worlds, though, which is also why GTA SA really excited me and it's one of my favorite open worlds. In GTA SA, there's a couple small towns outside of Los Santos or San Fierro that are very similar, but for the most part, Rockstar puts insane amounts of care into their open worlds... even 15 years ago when San Andreas was coming out. In the case of GTA SA, I don't think they could have packed that whole story into just Los Angeles, and so expanding into San Fracisco and Las Vegas (plus all of the rural places in between) really made the game feel like an epic urban journey to me. GTASA also did a great job of making every area feel so distinct, it's a hallmark of Rockstar's world design.
So, I think Rockstar is a little immune to this criticism, at least, more so than other developers are... Because while their worlds are also huge, they put so much care into them and usually make the places matter. As a marketing ploy, I do think that we've already stepped back from "The biggest world ever!!!" type stuff, specifically because of developers like Ubisoft who were rightfully criticized as having more or less "paint by numbers open worlds," where they'd sort of paint the environment on without a lot of care about how it's made.
For instance, in Far Cry, you can drop me into any place in those open worlds and most of them have no unique feel to them at all. They reuse a ton of assets around the world and a lot of areas will even use similar patterns for creating buildings and structures, layouts and more. This is in contrast to Rockstar which... like Red DEad Redemption 2 has
so much care put into its open world it's insane. I don't think any two buildings are the same model, and this is even like... horse stables.
The sheer size of an open world really doesn't matter to me anymore, but with developers who I know put a lot of care into their open worlds, like Rockstar, I know that I'm going to find a ton fo things I love in that world, so that excites me to explore it. So, if the Just Cause developer says "Just Cause 6 is the largest open world we've ever made!!" then that doesn't do anything for me, but when Rockstar says that their open world is the largest they've made, that carries more weight for me because I know that world will be so unique.
