Hi,
Air, Space, Land, ok these are places for adventure but, for me, there is a lack : the Sea
I mean, if a team wants to give huge ressources to another one.. you must declare permissions on the very tiny 128 m3 container.
1 / In my idea, it will be possible to build huge ship like tanker or container ship, the bigger interest is to ship a huge volume of material with a small engine...( like in reality where a tanker uses a very small engine if you compare it to the global mass of the ship ). In this case, the tanker could be declared like a vaste container ! ( For a builder like me, 128 m3 it's just a joke....) You could send a ship close to the shore and declare it like a primay container ...Then, build a town or a base or harbor will be made easier.
2 / Second interest : have an another surface for adventure, you need to protect a fleet for example, just like the Navy ! ( On the oceans, the territory hexagons must be removed...a the planet will must be bigger )
3 / Third interst : low fuel to move huge masses like a tanker in reality.
