Massively Multiplayer Online Games (MMOs) are online video games that allow thousands of players to interact and play together in a virtual world. Players create characters and can explore vast environments, complete quests, and engage in battles with other players or computer-controlled characters. Popular examples of MMOs include World of Warcraft and Final Fantasy XIV. These games often feature persistent worlds, meaning the game continues to evolve even when a player is offline. Players can join guilds or clans, participate in large-scale events, and trade items, fostering a sense of community. MMOs typically require an internet connection and may involve subscription fees or in-game purchases.
