The present doctoral thesis addresses the insufficient exploration of the concept of play style in current video game player's research. To reach the goal, theoretical framework of style as an intentional model of player's believes and desires is used. The main proposition of this particular paper is based on the presumption that play style works as a tool for predicting opponent's behavior. The research consists of two parts. The first one proposes a categorization which might in greater accuracy explain existing forms of play. The second part researches the topic of intentionality further through the procedural model of style prediction in progaming area, which is exemplified by the video game League of Legends. The results are based on extensive analysis of players' texts, interviews with semiprofessional players, commentators and game journalists. The conclusion implies a significant number of play styles and procedural complexity of recursive theory of mind ("I think about what you think that I think") in the field of video games. Keywords: Play Style, Intentionality, Intentional Model, Metagame, Metacognition, Mindgame, Progaming, Theory of Mind, Player Typology, Video Game

The aim of the thesis is to examine both Husserl's and Kant's transcendentalism in a way that would avoid the tendency to put the main accent on Husserl, which is an approach common to almost all literature dealing with this topic so far. Since it is for the most part Husserl's own critique of Kant that inspires such ongoing underestimation of Kant in comparison to Husserl, this work focuss on the question of the legitimacy of this critique. The core of the thesis is an original interpretation of Kant's transcendental philosophy which, instead of taking for granted the phenomenological point of view, attempts to describe Kant's philosophical enterprise from its own perspective and in its own right. In its second part, the thesis provides a brief description of how Husserl, starting initially from the position of descriptive psychology, arrives at a transcendental dimension. When so put side by side, it becomes evident that the two transcendental positions are in fact very different. Husserl's critique of Kant then appears as unjustified, even though quite understandable as an attempt to draw back from certain immature motives of his own philosophy.
