I’ll get straight to it.
Make the world flat! I know haha, flat Earthers would go crazy!!!!
You could make the edges a waterfall into the abyss!! Where you get a glimpse at the great turtle on the way down.
Also this could create a neat daylight cycle... the sun would be a spotlight that circles the map.... so theoretically you could have longer or shorter days depending on if your sailing with or against the sun... might be a bad idea but I thought it would be fun
Also you could create some unique areas that are at the edge of the world and they actually scale down a ways off the map... might be neat to be traveling down a path watching your step lest you fall into the abyss
Just thought this would be neat
