FOSS gamedev and creative worlds

I think if MT has a fake terrain in the edge or corner of the world (far land in MC) (to fill emptyness of void) it will be great.

Technically, this would be impossible with the current engine set up, it would take a lot of extra coding to make it work. However, a mod could do the next best thing: have the farthest 1000 blocks on each edge of the map have a sort of terrain like MC's Far Lands, although with a Minetest twist. Also, just have a single wall of blocks extending all the way up at the very edge that will teleport you to the exact opposite edge of the world, thus faking a wrap-around. Perhaps I could make something in that vein somewhere down the line.... (I already want to make an overworld gen of my own, perhaps I could include this idea in there...)

You could simply reduce the map limits by 100 nodes and that way you see into the distance but cannot travel beyond the 30,000 limit...
