Thera is a city-building and resource management game for 1-4 players, set in Ancient Greece. Your goal is to rebuild Thera after its destruction by a volcanic eruption. It is live on Kickstarter and the campaign will run for another 12 days. You may pledge for a copy of the game.
The game is played over 9 rounds. On your turn, you first choose one of the five roles available (Priestess, Worker, Builder,Trader, Planner). A role is available only if there is no player pawn on it. Then, all players carry out the Global Actions associated with that role. Next, you can spend coins to increase the Favor you have with this particular role. If you have enough Favor, you (and you alone) can also carry out the corresponding Favored Actions. At the end of your turn, you must collect all the original Favor accumulated on the role (your coins are discarded back to the supply) and then distribute it clockwise among the other roles of the rondel, one token at a time until none is left.
As part of their Global Actions, all roles activate the corresponding buildings of your own island on your player board. Besides that, the Priestess allows you to collect water. The Planner moves your resources (cloth, water, stone, and lumber) around your island and enables you (as part of a Favor action) to reserve a building from the central display so that you have the exclusivity to build it later on. You can build such a building (either reserved or directly from the central display) with the Builder Global Action, provided you can spend the cost of the building. Moreover, cloth, stone and lumber must be spent directly from the site you want to place the building on (coins can be freely spent from your personal supply though). With the Trader, you gain coins and can exchange resources.
In the solo mode, you play against an AI player, Plouteus. On his turn, Plouteus reveals a card to pick a role. He actually carries out very few global actions except building, automatically claiming the top-most, left-most building available.
When the end game is triggered, you win points from your buildings (with bonuses if you placed them on specific sites) and your collected resources. Plouteus scores points from his claimed buildings and from the cards revealed during his turns. There are several difficulty levels and, in higher difficulty levels, Plouteus also earns points throughout the game, depending on the card he drew and on the Favor tokens amassed on the role specified by his card.
If you get more points than Plouteus at the end of the game, you win!
