This assignment is about massive multiplayer online (role playing) games (MMOGs and MMORPGs). You have two options. Either you

• present an overview and comparison of architectural and interaction styles that can be found in these systems

or you

• concentrate on P2P and present a thorough discussion of this style and the variety in design for this style

In each case, you should use at least 3 of the articles listed below and take their content into account in your essay. You are, however, not confined to three articles, nor need any additional ones be taken from this list.

• Colyseus: A Distributed Architecture for Online Multiplayer Games
• Practical Middleware for Massively Multiplayer Online Games
• Agents-Based Modeling for a Peer-to-Peer MMOG Architecture
• A Distributed Architecture for MMORPG
• Towards Service Oriented Architecture (SOA) for Massive Multiplayer Online Games (MMOG)
• Peer-to-peer architectures for massively multiplayer online games: A Survey
• Requirements of Peer-to-Peer-based Massively Multiplayer Online Gaming
• A peer-to-peer architecture for massive multiplayer online games
• Publish/Subscribe Network Designs for Multiplayer Games

Your essay should

1. discuss the main concerns that drive the architectural design choices. This includes presenting the evidence the authors give for having realized the stated requirements and your own critical evaluation of that.
2. discuss whether, and if so how, the architecture allows the various players to maintain a consistent view on the game state
3. compare the architectures (designs) with respect to performance aspects such as, e.g., load distribution and required network bandwidth, and scalability.
