Final answer:
The true statement about MMOs is that they usually have vast online player communities and in-depth character development. MMOs are multiplayer and not limited to consoles, and roleplaying is a key part of the game experience.
Step-by-step explanation:
The correct statement about massively multiplayer online roleplaying games (MMOs) is: c) MMOs often have large online player communities and extensive character development. This is true because MMOs are designed to support large numbers of players simultaneously interacting in an online virtual world. The players assume the roles of characters and engage in a variety of activities within the game, often leading to elaborate character development over time. The communities formed in these games can be quite extensive, rivaling offline communities in complexity and social interaction.
Options a) and d) are incorrect because MMOs are by definition multiplayer and not limited to single-player experiences, and they are played on multiple platforms, including PCs and consoles. Option b) is also incorrect as roleplaying is a core element of MMOs, allowing players to create and inhabit a character within the game's universe.
Real-world economics have found their way into these virtual worlds, with some players making real money through the management and trade of in-game assets, such as real estate or currency. This has led to a convergence of the virtual and real economies, illustrating the significance of these games for certain individuals and groups.
