PS4 FF7 Remake

They are both two different things, an you could even have large OPEN locations within a map. An open world can have many locations if divided correctly, it's not just one big location like you suggest.

At least the worst thing that can happen in a map is that you have to fight lots of monsters and nothing else.
Dragon Dogma clearly wasn't divided correctly, at this point i might even have played to the worst RPG open world possible, (which is something you should never do as first experience...) anyway...

Why would an open world FF7 would automatically have MMO RPGs beginner's quests? Why would Cloud need to collect 10 tissues before being able to ride the shuttle to the gold saucer? Why would draw points in a FF8 remakes make more sense out in the grass in the middle of nowhere on a mini-map rather than in an actual location under a suspect object? I'm applying your logic to other games because frankly it doesn't stand on solid grounds. Why does everything in an open world is unnecessary shit (treasures, loots, etc...) but is ok and suitable for an empty/invisible spots? Is a loot won from a monster in a open world uneccesary but not from a random encounter? Are you talking about MMO RPGs again, which what the remake will not be? Is FFXII full of uneccesary shit because it contain open world locations?

as i wrote after not all open world necessarily have all the 3 points at the same time, draw points are not useless(and there are also secret spots of them, both in map and submaps)
Perhaps i should define better what is unnecessary shit... something like 2000000 items with more or less the same effect(or not even an effect) or an useless effect, that you keep to find everywhere, crushing your hopes of finding something interesting finally, that also defeats the purpose of explore any single zone of an open world
NOTE: yes that still comes from Dragon's Dogma and i'm pretty sure that will never happen in FF(right?!?)
The closest thing it comes to my mind are FF12 loots that can only be sold, but at least you clearly know that they have no other use aside that(not that i loved too much that FF12 feature...)

I can understand that, but the purpose of a wold map in PS1/SNES RPGs is not to simplify the world because there is NOTHING to simplify. You can't decide to investigate and look closer on a certain path you're walking because the only place you can see in details is town A you just left and cave B you're going to. Writing that makes me realize an open world with a smaller scale map to travel faster would be a good option.

Actually yes, for example in an open world if you go through a forest, you'll start to search trough all trees of the forest for something or someone and you'll probably spend a whole day for do that and maybe without even accomplish your goal or finding a clue.
In a world map there's just a not too big spot and even in the case you wanna explore any single piece of it, you'll be able to do that in less than 10-20 minutes, which is way more reasonable, even if you don't find anything, if there's something to hide you'll trigger something at a certain point or enter in a submap in which you can explore the forest better.
A smaller scale might be something, but(for example) Dragon Quest VIII had an insanely huge world map, even if you might spend days exploring that it would still be worth to do.
My impression about open world is that what makes them last long is the number of hours wasted during travels, world map games could even last around 100 hours but you always do something significant and you hardly spend all that time for world map travels... i think open world's length is "fake" length, like if they give you a huge area just to hide that the game is actually poor of real contents.

Having a linear world map is not good either

Never said that, but in FF2 there almost were "no borders" to limit the first area of world map, it was quite easy to lose your way and waste a whole day/s in random fights and nothing else

Even then, early RPGs had to plan everything in order to restrict your exploration

probably this is one of the main reason why i think they are better: because they had to plan everything... there's more planning on the maps there than in an open world, i'm not talking about make a map... i'm talking about design, calculate a map think to obstacles and how to design it in order to make accessible a certain areas in a certain moment, and it's not the invisible barrier or a closed door, rather than mountains, rivers or sea that type of obstacle.

you can't deny that world maps were born more from technological limitations rather that an actual choice or preference

There's no doubt i can't deny it, at the same time you can't deny that new technology became an actual limitation to game contents.
even with new technology now they need of split the whole game in slices, all in exchange of graphics.
Among the two i choose game contents.
