4X is a genre of strategy-based games in which players control an empire and "eXplore, eXpand, eXploit, and eXterminate". Emphasis is placed upon economic and technological development, as well as a range of non-military routes to supremacy. Games can take a long time to complete since the amount of micromanagement needed to sustain an empire increases as the empire grows.

A subgenre of the adventure game, point-and-click games typically involve interacting with background objects, talking to non-player characters, and using an item inventory to solve puzzles that allow the player to progress through the story.
