Massively Multiplayer Role-Playing Games
MMORPG is a multiplayer computer role-playing game that enables thousands of players to play in virtual world at the same time over the Internet.
Players run a client to connect to an MMORPG and someone else, usually the game's publisher , hosts the game world. Most MMORPGs are commercial and require the player to pay a monthly fee in order to play. The virtual worlds they create are called "persistent worlds", meaning that the world continues regardless of who is logged in or not. When a player logs in, they are represented in the game world by an avatar — a graphical representation of the character they play.
In many MMORPGs, the economy becomes unbalanced over time due to inflation and can reduce meaningful interaction between players of varying level (i.e., newbies versus more powerful players). This is primarily due to the gradual accumulation of wealth and power within the game. Some MMORPGs have addressed this with varying degrees of success. The theory being that it is in the interest of higher level players to assist the lower players and thus increase the reward they receive.
