The game world of Red Dead Redemption 2 is huge. But you won't be able to estimate its scale at the very beginning of the game: the full version opens gradually as you complete missions. However, as in many cases, it is possible to use a cheat code that will help correct the situation.
The game is RDR 2 begins in the North, near the gorges of the Spider. Then the main character's path will lie to the South, through Amberino, to New Hanover. In addition to Leymon, they make up the North-Eastern part of the map, where half of the gameplay will take place.
South of Lemoyne, the effect is almost non-existent. Next, Arthur will travel to West Elizabeth County, where Blackwater is located. Access to this part of the map will open after a failed Bank robbery in Blackwater.
Don't go straight to West Elizabeth. It makes sense to explore the entire northeast of the map first. And only then start moving in that direction, including visiting Austin. However, keep in mind that visiting most places in these regions is restricted by law for the main character. Therefore, it is better to wait until the status of "wanted" is removed from Arthur first.
You can unlock the full map gradually as you progress through RDR 2.You can also use a cheat code and buy a full map. This will be possible in Saint-Denis, after completing the "Blood Fueds, Ancient and Modern" mission in Chapter 3.
After purchasing the card, you just need to enter the phrase "you looked for a long time, but you don't see anything in the cheats section of the red Dead Redemption 2 menu". (You long for sight but see nothing into the cheats section of the Red Dead Redemption 2). This will help you see the full version.
