A Massively Multiplayer Game (MMG) is an Internet-based distributed game (or multiplayer game) that supports a large amount of simultaneous players interacting, in real-time, in a persistent virtual world. Practically all of today's MMGs employ a client-server distribution approach where the client is trusted only to send interaction requests and receive(More)
State-of-the-art Massively Multiplayer Games such as EverQuest and Ultima Online are currently implemented as client-server systems. Although this approach allows the development of commercially viable MMG services, the costs associated with running a scalable client-server MMG service are often too high for small companies or research projects.

The ubiquitous computing scenario brings many new problems such as coping with the limited processing power of mobile devices, frequent disconnections, the migration of code and tasks between heterogeneous devices, and others. Current practical approaches to the ubiquitous computing problem usually rely upon traditional computing paradigms conceived back(More)
We propose a peer-to-peer event ordering and simulation technique aimed at networked real-time action games. Partially based on replicated simulators, its goal is to support decentralized playout in small-scale game sessions on instanced action spaces while being resistant to collusion cheating. The action spaces are linked to persistent-state social spaces(More)
