Interesting idea, but this would take a lot to implement, maybe this could be a novelty world just for fun in future.
I know this is an old thread, but its not closed off, so I'll give my comments.
I agree with what the mods have said, I dont believe that from a software engineering perspective that this could be done without a GIGANTIC change to the game that would mean Grepolis 3.0 with users having to pay say 10x what they currently do for gold.
However, I do think there is a comprimise here. Currently there is two types of islands, being "island" (7 x 3) and "tiny island" (3x3) with island having 20 cities & 8 farms, whereas tiny island having 10 cities and no farms. I would recommend a third type of island being "continent". Each ocean would have four continents in that ocean. Each continent would be (eg) 20x10. Each continent would have 60 sea-cities, 21 land-cities and 24 farms in three provences (ie: 20 sea, 7 land & 8 farms per provence).
Each provence would be bordered off by mountains, so that each land city can only be attacked by the 20 sea & 7 land in their provence. Each city can only access the 8 farms in their provence. Building a wonder should only be allowed on a continent (no islands or tiny islands) and only with all 21 land-cities being under the control of the alliance.
