Samenvatting

This is a report about a graduation project performed at Delft University of Technology. To test some of their gaming related research in a real life environment, they are setting up a platform called @Large. This platform will add massive multiplayer components to several games. The first game to support this platform is
OpenTTD, an open source real time strategy game.

The goal is to have four different multiplayer types for OpenTTD: a quick game, the normal game, a scenario and the "unlimited game". In a quick game the player needs to achieve certain goal within 15-20 minutes, the normal game is almost the same as the default OpenTTD multiplayer with a few additions, scenario games have scripted events, and the player needs to achieve one or more goals, and an unlimited game is a infinite map with an infinite amount of players with a different set of rules: the number of actions a player can perform on a single is limited, and new technology becomes available when certain achievements are unlocked.

This goal of this graduation project is to bring the @Large platform a bit closer to this goal for OpenTTD. Things to implement in this thesis are the possibility to actually select a type of multiplayer game, and a game independent achievement system for @Large, which can be used as base for the unlocking mechanism in the unlimited game. Early in the project it was also decided to refactor a lot of code to C++.

The project went rather successful. The achievement system does not have an implementation yet, but the designs are available. The reason the achievement system is not finished yet is because the refactor to C++ cost a lot of time.
