Round based online only strategic economy game MMOG with PvP und Coop
elements.
No prior knowledge of famous paintings and painters required.

The year is 1916. World War I is raging and many famous paintings of well
known artists have vanished in the turmoils of war and have been scattered
all over the world. Art enthusiasts from any corner of the world have made
their business to complete their collections. And you are one of them!

The only problem is the limited availability of financial resources needed
to acquire the expensive pieces of art in auctions. In order to make
money you have to decide whether you would rather be a plantation owner
growing, harvesting, shipping and selling different crops or whether you
would rather like to try your luck with stock speculations.

If neither of both ways leads to a great fortune there is still the option
to attack and rob your opponents. But be aware that those who have money
will probably know how to protect themselves.

However, the ones with the greatest wealth will have the best chances to
win the auctions of famous paintings by painters like Vermeer or Van Gogh.
The first to complete a collection wins the round! Unfortunately there are
many forgery on the market, so that you can only be certain about a
specific painting after getting an expertise.

Vermeer-Mobile is a homage to a similar game from the 1980s for the C64,
enhanced by PvP and Coop elements. The game is in an early state of
development is being constantly worked upon.

[GAME ROUNDS]
A game round always starts at the 1st of January 1916. It ends when a
player or a gallery owns a complete set of original paintings of one
painter. Then all players begin from zero again and all resources are
reset. The only thing that remains across all game rounds is a leader
board which contains the points earned for the players' achievements.

[COOP]
When a player owns 3 paintings he cannot travel anymore. But traveling is
an fundamental ability. So, in order to put some of his paintings into a
gallery the player will either have to found a gallery or become a partner
of an existing gallery. Up to 7 players can be partners of a single
gallery and try to win the round together. So grab some friends and off
you go!

[PvP]
Since there are more players than collections of paintings (the owner of a
complete collection wins the round), you will sooner or later face the
problem that other players are in possession of a painting which you are
missing in your collection. No problem! Develop your own criminal
organization with as many members as you are able to manage. You can
assign different tasks to each member, e.g. sabotaging other players'
plantations, robbing their harvest and much more. One of the missions is,
of course, stealing paintings from other players. It is also possible to
use your members defensively and then confrontations are inevitable.

App-Permissions
The permission to read/write your memory is needed only if you want to
upload a profile picture. Permission to set an alarm is only needed if you
would like the app to set alarms for upcoming auctions. This uses the
default timer app that is installed on your device.
