Unknown Horizons

There’s no shortage of real time strategy games, but many are simply clones of each other. Fortunately, Unknown Horizons is a notable exception. This 2D RTS game from the Unknown Horizons Development Team focuses on city building and economy, but it has a lot of extra features that make it stand out from the rest. It all starts with a small settlement, and from there you can expand into a powerful colony.
