IF you never added limit to map size, you most likely won't get why I sugest this. The space Exploration (mod)'s planets are a better exemple why this sugestion would make the game more interesting and enjoyable

TL;DR

Make planets wrap around, so when reaching the map edge, you can't tell because you just passed onto the other eage, on the opposite side—making the world feel round instead of flat.

What?

I suggest changing the way planetary maps work by making them edgeless, or rather, looped. This means when a player reaches the edge of the map—whether horizontally, vertically, or diagonally—they seamlessly appear on the other side, continuing movement without interruption.

This would simulate a round planet instead of a flat, bordered area. There would be no visual corner, no visible limit—moving diagonally would eventually lead you back to your starting point from the opposite side, without hitting a "map end."

Why?

Because right now, the world is just an infinite flat planet, and when you reach the end breaking immersion.

It’s a feature that would greatly enhance immersion and make the planet feel like a real, continuous world, not just a big square.

And the best is traveling with trains

What? You completely lost me, why would you ever want that. It that something anyone experience, ever? You may have seen that on Google Maps or whatever, but in real life? No realism here, no value added if this were to be implemented, it would only confuse people.

In the scale of how unlikely this it, it goes up to 11. If this would be part of the design 13 years ago then maybe, but right now that is way outside of what we would ever want to do. Having a rectangle world wrap around would require literally all of the game logic to account for that including distance measurements across the seam to tell a biter and turret are next to each other and there is no need to travel across entire map. All mods would be broken, all entity searches would have to account for that, all lua api would have to account for wrap around of coordinates.

Just no.

If you loop both horizontally and vertically, that would actually be a torus-shaped planet

Lots of games do that anyway of course, but it doesn't correspond to how a spherical planet would work. I'm not sure this really adds much to Factorio, but in general if you do want to make a flat 2D map "feel" like a round planet without having to use spherical geometry (see Dyson Sphere Program for an example of the somewhat awkward consequences that can arise), the "usual" trick is to have it wrap east/west but block the north/south ends of the map with impassable terrain like ice caps, so you can just pretend the poles don't exist and not have to deal with it :p
