abstract = "We investigate user-guided evolution for the
development of virtual 3D building structures for the
prototype (commercial) game Subversion, which is being
developed by Introversion Software Ltd. Buildings are
described in a custom plain-text markup language that
can be parsed by Subversion's procedural generation
engine, which renders the 3D models on-screen. The
building descriptions are amenable to random
generation, crossover and mutation, which enabled us to
implement and test a user-driven evolutionary approach
to building generation. We performed some fundamental
experimentation with ten participants to determine how
visually similar child buildings are to their parents,
when generated in differing ways. We hope to
demonstrate the potential of user-guided evolution for
content generation in games in general, as such tools
require very little training, time or effort to be
employed effectively.",
