Ikariam
The aim of the game is to expand the town which is controlled by a player, to gather resources and conquer other players. The game can be played for short periods of time. The player can build and research and it is during real time so the player can return at a later point and assign the town's people a new tasks. Upon registering, players are given control of a small town. The town's people pay taxes to the player or can be sent to gather resources instead. The game world is split into islands, each of which can support up to 16 (or up to 17 if the player purchases ambrosia) players and their towns. Each island has a structure called a Saw Mill. There are four types of islands, one is a crystal, one is sulfur, one is wine, and one is marble. With those four resources the player may construct buildings such as barracks, shipyards and academies. Citizens of the town can then be trained as soldiers, sent to research new technologies, or perform other tasks, which they are paid tax money for undertaking. Citizens must be kept happy to prevent them from leaving the town. Citizens happiness factors change multiple ways, the construction of a tavern is one of the best ways to gain happiness. Another way to gain is by building museums and set up cultural treaties with other players.
