It introduced many unique conventions such as the ability to design your own spaceships, balancing the available space and cost, and strategically researching technology to counter the enemy's ships. It is also notable for its highly distinct races requiring very different strategies to beat the game. Alan Emrich first described the "4X" game genre in which players control an empire and "explore, expand, exploit, and exterminate" when reviewing Master of Orion. This genre is characterized by deep and complex gameplay, of which Civilization (from 1991) is also a good example.
1993 - Adventure: Myst (Cyan Worlds) - Myst popularized a new style of puzzle-based adventure games.
1993 - FPS: Doom (id Software) - Doom further popularized the FPS genre and pioneered realistic and immersive 3D graphics, networked multiplayer gaming and support for custom expansions.

It's use of a tough female heroine - Lara Croft (rather than the typical male action hero) was both revolutionary as well as derided as sexist because of her exaggerated physical features. Lara has since become a major video game icon and the series led to two Hollywood films.

It has been criticized by notable figures such as Hilary Clinton.
2004 - MMORPG: World of Warcraft (Blizzard) - Although not particularly innovative, it borrowed the best features of its predecessors and made RPGs more accessible to casual players.
