Large world similar to Anno games with big oceans and small islands

Hi there, really interested in your product. I was wondering if it is possible to create a system similar to Anno 2070 where you have a world size of say 4096 x 4096 unity units with mostly ocean and smaller islands. Boats can travel between islands, and buildings of 1 x 1 unity units can be placed on islands. People can walk on islands only.

Hi

Yes, that is possible.
A 4096x4096 grid graph would be way too large to fit nicely in memory though, so I would recommend creating smaller grid graphs, one for each island (or possibly a group of islands). The ships would have to use some other kind of pathfinding (if they even need one). Possibly you could use a point graph for that.
