why only isles?

[Wolf01]

now you can create only isles with the scenario editor, but all other simulation games, like sim city, allows to build the terrain close to the edges to make all flat, a peninsula or a gulf/beach
why not make it possible?

TTD used the outer tiles to save on special conditions for the main drawing loops, so they had to be consistent, and CS decided that water was the way to go. OTTD is trying to stay compatible (How long will this last?), so it has to do things the same way.

You can hack the savegames with a hex editor. It's possible to make the whole map be land.

This is an original screenshot taken from one of my savegame experiments:



EDIT: BTW, the edge doesn't have to be flat, it can be of any height, as in RCT.
