Ragnarok Online

Ragnarok Online often referred to as RO, is a massively multiplayer online role-playing game or MMORPG created by GRAVITY Co., Ltd. based on the manhwa Ragnarok by Lee Myung-jin. It was first released in South Korea on 31 August 2001 for Microsoft Windows and has since been released in many other locales around the world. Much of the game's mythos is based on Norse mythology, but its style and settings have been influenced by a wide variety of international cultures. The game has spawned an animated series, Ragnarok the Animation, and a sequel game, Ragnarok Online 2: The Gate of the World, is in development. Player characters interact in a 3D environment but are represented by 2D character sprites for front, back, side and diagonal facings.

Ragnarok Online is divided into a series of maps, each of which has its own terrain and native monsters, though many monsters are present in multiple regions. Transportation between maps requires loading the new map and monsters cannot travel from one map to another.

There are three major nations in Ragnarok Online, the first of which and where all players start is Rune Midgard. The Schwaltzvalt Republic, an industrialized neighbor to the North, was added in Episode 10 and Arunafeltz, a religious nation modeled after a combination of Israel and Turkey is the subject of Episode 11.

A series of other, minor nations also exists, generally modeled after an ancient society in the real world, examples such as Amatsu, which is modeled after ancient Japan, and Louyang, which is modeled after ancient China.

Areas from Norse mythology are also included, such as Niflheim, the land of the dead, and Valhalla, where players can become Transcendent Classes. New map content is constantly being added to game in the form of Episode updates.

Gameplay:
Ragnarok Online is a massively multiplayer online role-playing game, where players can create several characters per account, but can only control one character at a time. Basic gameplay involves killing monsters wandering around the game world in order to gain experience and level up. This is referred to PvE combat. Players can accept optional quests from non-player characters for special rewards and to flesh out the game's fantasy world. An extended series of quests have to be completed for most job advancements. There is no main narrative, and players are free to explore the game world in a non-linear manner.

Half-Life Counter-Strike

Counter-Strike is a first-person shooter in which players join either the terrorist or counter-terrorist team (or become a spectator). Each team attempts to complete their mission objective and/or eliminate the opposing team. Each round starts with the two teams spawning simultaneously, usually at opposite ends of the map from each other. A player can choose to play as one of eight different default character models (four for each side, although Counter-Strike: Condition Zero added two extra models, bringing the total to ten). Players are generally given a few seconds before the round begins (known as "freeze time") to prepare and buy equipment, during which they cannot attack or walk/move (a player can still take damage, having the player drop from a certain height during freeze time was the only way somebody could control the players starting "HP"). They can return to the buy area within a set amount of time to buy more equipment (some custom maps included neutral "buy zones" that could be used by both teams). Once the round has ended, surviving players retain their equipment for use in the next round; players who were killed begin the next round with the basic default starting equipment.

Standard monetary bonuses are awarded for winning a round, losing a round, killing an enemy, being the first to instruct a hostage to follow, rescuing a hostage or planting the bomb.

The scoreboard displays team scores in addition to statistics for each player: name, kills, deaths, and ping (in milliseconds). The scoreboard also indicates whether a player is dead, carrying the bomb (on bomb maps), or is the VIP (on assassination maps), although information on players on the opposing team is hidden from a player until his/her death, as this information can be important.

Killed players become "spectators" for the duration of the round; they cannot change their names until they spawn (come alive) again, text chat cannot be sent to or received from live players; and voice chat can only be received from live players and not sent to them (unless the cvar sv_alltalk is set to 1). Spectators are generally able to watch the rest of the round from multiple selectable views, although some servers disable some of these views to prevent dead players from relaying information about living players to their teammates through alternative media (most notably voice in the case of Internet cafes and Voice over IP programs such as TeamSpeak or Ventrilo). This form of cheating is known as "ghosting".

Defense of the Ancients (DOTA)

DOTA is a custom scenario for the real-time strategy video game Warcraft III: Reign of Chaos and its expansion, Warcraft III: The Frozen Throne, based on the "Aeon of Strife" map for StarCraft. The objective of the scenario is for each team to destroy the opponents' Ancients, heavily guarded structures at opposing corners of the map. Players use powerful units known as heroes, and are assisted by allied heroes and AI-controlled fighters called "creeps". As in role-playing games, players level up their hero and use gold to buy equipment during the mission.[2]

The scenario was developed with the "World Editor" of Warcraft III: Reign of Chaos, and was updated upon the release of the expansion, The Frozen Throne. There have been many variations of the original concept; the most popular is DotA Allstars, which has been maintained by several authors during development. The current developer is known by his pseudonym as "IceFrog", and has been developing the game since 2005.

Since its release, Allstars has become a feature at several worldwide tournaments, including Blizzard Entertainment's BlizzCon and the Asian World Cyber Games, as well as the Cyberathlete Amateur and CyberEvolution leagues; Gamasutra declared that DotA was perhaps the most popular "free, non-supported game mod in the world"
