Tile-based video game
（重定向自Tileset）
A tile-based video game is a type of video or video game where the playing area consists of small rectangular, square, or hexagonal graphic images, referred to as tiles. The complete set of tiles available for use in a playing area is called a tileset. Tiles are laid out adjacent to one another in a grid; usually, some tiles are allowed to overlap, for example, when a tile representing a unit is overlaid onto a tile representing terrain. Tile-based games usually simulate a top-down or "2.5D" view of the playing area, and are almost always two-dimensional.
