Oasis is a strategy game combined with a lightweight version Civilization game. You start the game with some followers and your job is to find cities, earn money, develop technologies, gain more followers, and uncover the secret obelisk.
You have limited turns to move before the barbarians attack your cities. So every move counts. To defend your kingdom, you have to develop technologies and build followers. When you click something on a tile, it reveals something new. The secret obelisk has magical power that can earn money for you or increase the number of available turns.
Even though the graphics and sounds are not great but the gameplay of Oasis is very fun. It requires some simple strategy and planning.
