this feature would extraordinarily reduce micro management, and that is what this game is about.
because it is supposed to be something rare, as in if you could use it to much the game could become really easy, having this ability, should be something that you earn
this would limit the amount of times a unit could be teleported, making it a both rare and powerful structure .My solution to this is that when placing flags or buildings, there is an option allowing units working on it to travel through the obelisk, if there is one near to the worker/ warrior and an obelisk close to the target destination the unit will travel through the obelisk.
Also it could work like an inn in some ways, that each teleportation costs papyrus, cost would be higher per warriors. when the papyrus supply gets low, units cant go. Another thing that would have to be figured out is how to not allow units to randomly go through at will, because papyrus does not regenerate.
to each of those equations add the basic cost of the ship. which i forgot to add.
The docks could only have a certain amount of ship space, when a ship is at sea and the port does not have a spot it will float around until one becomes available. There could also be passanger boats for ferring, and warships, cost more. When a ship is destroyed at sea all blobs would die, on shore they will survive, when port is destroyed it would destroy all ships docked at it.
I agree with Zerothis, also the ship should have a certain capacity of the amount of blobs it holds, and should cost A x B
A=cost of worker + cost of warrior
B=amount of blobs ship can hold (capacity)
the ship should have hitpoints of A x B
A=hitpoints of worker+hitpoints of warrior
for instance, you are being attacked, and you want to build a defense tower to stop incoming warriors. But with all the warriors going back and forth the grass has dissapeareed. Now you have to wait until the grass grows back, by which time half of your city could be destroyed.
The problem i see with this is that when you have lots of workers/warriors, and a strong economy. but you are trying to expand. the places for you to build on would start to disapear with all of the walking, and you would no longer be able to build there.
It would be usefull, because enemy workers allways try to take your wheat and trees on scarse maps. adding a gate would allow them not to get your rescources, and thus disrupt your conservation of rescources.
