While there has been much research done on player modeling in single-player games, player modeling in massively multiplayer online role-playing games (MMORPGs) has remained relatively unstudied. In this paper, we survey and evaluate three classes of player modeling techniques: 1) manual tagging; 2) collaborative filtering; and 3) goal recognition. We discuss the strengths and weaknesses that each technique provides in the MMORPG environment using desiderata that outline the traits an algorithm<span class="external-identifiers"> <a target="_blank" rel="external noopener noreferrer" href="https://doi.org/10.1109/tetc.2014.2360463">doi:10.1109/tetc.2014.2360463</a> <a target="_blank" rel="external noopener" href="https://fatcat.wiki/release/bll2mpkj7bgqllkxfxwckexkje">fatcat:bll2mpkj7bgqllkxfxwckexkje</a> </span>

We also discuss how each of these classes of techniques could be applied to the MMORPG genre. In order to demonstrate the value of our analysis, we present a case study from our own work that uses a model-based collaborative filtering algorithm to predict achievements in World of Warcraft. We analyze our results in light of the particular challenges faced by MMORPGs and show how our desiderata can be used to evaluate our technique.
