MMOG is an abbreviation for Masively Multiplayer Online Game. As in an MMORPG, this term describes a large number of users who navigate through an MMOG using an avatar in a virtual world. The difference between MMOG and MMORPG is that an MMORPG requires the user to create a character outside of him or herself to engage in role-playing. An MMOG includes virtual worlds where the user´s avatar is a reflection of him or herself in real life. Twinity is defined as an MMOG. Twinity members represent themselves in the 3D virtual world as themselves – they can use their real names, create an avatar that physically represents their real selves (using Twinity’s PhotoFit feature) and be who they really are in the physical world inside the Twinity virtual world.
