Analysis of a particular segment of the gaming industry market has given us useful information regarding the specifications of games that are highly sought after by the community of that particular game. Such analysis, done as a part of this thesis, has included 6 games of a particular genre. The result was a set of popular specifications that served as a basis for a development of the game that was being developed as a subject of this thesis. The idea behind this approach is that having such knowledge in a planning phase of the game development can greatly increase its chance of successful reception by the community of a given genre, thus returning the resources invested in the analysis by minimum. Results of the analysis are that the most sought-after features of the games in question are multiplayer and achievement system. Other features are much more specific like better inventory management, better character interaction, etc. Second part of the thesis is focused on the development of the game. It contains the explanation of the game infrastructure and the manner of implementation of said features. Some design decisions are also explained and their merits laid out, like a decision to use the MVC architectural pattern and the heavy use of the class inheritance of object oriented programming paradigm.
