Role Play Worlds (RPW) is a massive multiplayer online role play game, a 3D virtual world, built by AET (a role players association) and the residents, aimed 100% for different thematic role play realms. Users use a software called a viewer to access the 3D world and interact as an avatar with other users and engage in role play, build complex 3D objects (using primitives, meshes, importing from 3rd party software, etc), participate in community events, sell or buy virtual goods, out of character activities, etc. The combat system is based in a class A role play system known as L.A.R.P.S. (Legacy Role Play System) that bring life to the avatars, adding race and class skilss, spells, levels, and tons of rp features.

The “worlds” concept relies on the user's initiative as a way to give creative freedom to the residents to build kingdoms but guided by Role Play Worlds in order to join that creativity into a organized concept.
