  Video games demand is constantly increasing, which requires the costly
production of large amounts of content. Towards this challenge, researchers
have developed Search-Based Procedural Content Generation (SBPCG), that is, the
(semi-)automated creation of content through search algorithms. We survey the
current state of SBPCG, reporting work appeared in the field between 2011-2022
and identifying open research challenges. The results lead to recommendations
for practitioners and to the identification of several potential future
research avenues for SBPCG.
