World of Warcraft
"World of Warcraft" was first announced by Blizzard at the ECTS trade show in September 2001. Released in 2004, development of the game took roughly 4–5 years, including extensive testing. The 3D graphics in "World of Warcraft" use elements of the proprietary graphics engine originally used in "Warcraft III". The game was designed to be an open environment where players are allowed to do what they please. Quests are optional and were designed to help guide players, allow character development, and to spread characters across different zones to try to avoid what developers called "player collision". The game interface allows players to customize appearance and controls, and to install add-ons and other modifications.
Call of Duty: World at War
"Call of Duty: World at War" was released for the Nintendo DS on November 11, 2008 in North America, and on November 14 in Europe. It was published by Activision and developed by n-Space, who used the same game engine as their previous title, "". The game's scenarios are also based on World War II's Pacific theater and Eastern front with American, British and Soviet campaigns. Up to four players can be supported online with four different types of game, as well as perks and rank-ups. Compared to "Modern Warfare", it has improved in-level geometry, has more responsive sprints and crouches and 3D-modeled guns instead of 2D sprites. However the flamethrower, which is new to the game series, is rendered with 2D sprites. The framerate is just under 30 and has lots of voice-over during the missions. Players are able to defuse mines and send Morse code with the touch screen, as well as using mortar rounds, an anti-air gun from a battleship, parachuting and using mounted guns. There is also a tank mode which allows the player to turn the main gun and fire machine gun rounds at the same time.
