Query: Deriving Quests from Open World Mechanics   Open world games present players with more freedom than games with linear
progression structures. However, without clearly-defined objectives, they often
leave players without a sense of purpose. Most of the time, quests and
objectives are hand-authored and overlaid atop an open world's mechanics. But
what if they could be generated organically from the gameplay itself? The goal
of our project was to develop a model of the mechanics in Minecraft that could
be used to determine the ideal placement of objectives in an open world
setting. We formalized the game logic of Minecraft in terms of logical rules
that can be manipulated in two ways: they may be executed to generate graphs
representative of the player experience when playing an open world game with
little developer direction; and they may be statically analyzed to determine
dependency orderings, feedback loops, and bottlenecks. These analyses may then
be used to place achievements on gameplay actions algorithmically.
