SimCity 5 (2013) is the latest installment by Maxis in the SimCity series.

The game focuses on smaller building plots than previous games while increasing interaction with neighboring cities. The game saves are purely cloud based, and the game requires a constant internet connection. The game is described as a city-simulation MMO, although I am not sure you could consider a maximum of 16 players an MMO. The game can be played as a single-player but this still requires an internet connection and all saves are still cloud-based.

The game is set to contain aircraft, armored vehicles, and ships from the pre-World War II era to the early Korean War era. Some maps in the Historical Game mode are similar to real life WW2 conflicts. i.e Pearl Harbor.
The average size of maps in the game, currently range from approx, 100km x 100km to 200km x 200km. Although the engine powering the game is likely to archive larger map sizes in the future.

Spiral Knights is a massively multi-player online role-playing game developed by Three Rings Design and published by Sega. In the game, the player controls a knight of the Spiral Knights order, which has crash-landed on the mysterious planet Cradle.

The knights equip armor and weapons to aid them in their battles against the monsters inhabiting the Clockworks.

Rift is a MMORPG set in a fantasy world called Telara, which is the focal point of several different elemental Planes. These Planes are realities representing the elemental forces of Air, Fire, Water, Earth, Life, and Death, and it is at the one point where every one of these Planes intersect with each other that Telara exists. Each Plane is governed by a Dragon-deity, which is the personification of that elemental force.

X-Plane 10 Global is the world’s most comprehensive and powerful flight simulator for personal computers, and it offers the most realistic flight model available.

X-Plane is not a game, but an engineering tool that can be used to predict the flying qualities of fixed- and rotary-wing aircraft with incredible accuracy.

Guild Wars 2 is a massively multiplayer online role-playing game in development by ArenaNet. Set in the fantasy world of Tyria, the game follows the re-emergence of Destiny's Edge, a disbanded guild dedicated to fighting the Elder Dragons, a Lovecraftian species that has seized control of Tyria in the time since the original Guild Wars. The game takes place in a persistent world with a story that progresses in instanced environments.

Players take on the role of students of Wizardry to save the Spiral (which is the set of worlds this game takes place in), and battle a variety of creatures by casting spells using a turn-based combat system similar to collectible card. Players advance in the game by accepting quests to learn new spells, gain equipment, and collect gold. The game holds a rating of "Everyone 10+" from the Entertainment Software Ratings Board for crude humor and mild fantasy violence. Although designed for pre-teens, the game appeals to all ages.
