i don't know how i should go about this. i'm making my first open world game as a hobby project, but i don't know how to do the borders. should i put a wall of rocks like watch_dogs does? but that just looks unnatural... what about an invisible wall with just an endless field like fallout 3 does? it looks natural, but i think its impractical, i know i would get pissed if i ran into a random invisible wall in the middle (or edge, in this case.) of nowhere, especially if i haven't looked at the world map in a while. i don't know how to do it the right way, any suggestions are appreciated.
