FOSS gamedev and creative worlds

Most of people knows Agario dots game.
Today i have seen a mapgen which looks like 3d agario
Just a suggestion for a subgame if we could have owned an island and eat islands we could play 3d agario style game

Here is the mapgen

How would you move those islands?
If they were entities - no problem - but spheres with about 100 nodes can't be moved that easily.

how about to make them like a boats mod. if you touch another you became bigger boat (sphere)

Whoa I was thinking about this recently.
IMHO it would be a dedicated subgame, not something you can add to other servers

What if you made it so that each node you touched made you bigger (by about 1 node) and if you were close enough to a node you could mine it (which would automatically increase your mass)
