### Concept Tags: Game Development Aspects  
Table 3 presents the top 10 concept tags relative to the metrics described earlier. As stated before, these tags refer to generic terms encompassing various aspects relevant to game development: handling of _shaders_ (shaders are computer programs that run on graphics hardware and provide a high degree of control over how scenes are rendered), _textures_, _sprites_, _rendering_, and _graphics_ in general, as well as _collision detection_, _animation_, and _physics_ in general. \begin{table}

Table 3: Top 10 of all concepts tags for all the considered metrics. With respect to the number of questions, the tag \(2D\) is the most used (1593 questions) and dominates \(3D\) (sixth with 779 questions) across all metrics. It is followed by _collision-detection_ (second with 1173 questions), _physics_ (third with 1021 questions), and _shaders_ (fourth with 980 questions). Here again, using the average number of views helps to highlight a different set of tags, mostly with fewer questions. The top tag here is _aspect-ratio_ (with an average of 4483 views), followed by _terminology_ (second with an average of 3039 views), _balance_, _file_, and _cross-platform_. When it comes to favourability and score, the top tags include _balance_, _monetization_, _terminology_, _file-format_, and _npc_ (non-player characters). In addition, the average metrics bring into light a number of tags related to publishing and advertising the games, with tags such as _publishing_, _marketing_, and _monetization_. Most of the concept tags in our dataset are related to the rendering and animation of 2D (or 3D) characters or scenes, along with fundamental notions from physics and mathematics. However, some concepts are exclusively about gaming: mostly game genres (card game, puzzle, role playing game, etc.) but also aspects such as game design, leaderboards, and controllers. Among game genres, role playing games (rpg) are the most asked about (154 questions) followed by massively multiplayer online and real-time strategy games. Overall, concepts exclusively about gaming appear as tags for 3203 questions, which is only about 12.5% of our dataset.
