### Community Support for Concept Tags  
Figure 6 presents the distribution of concept tags along the failure rate and wait-time axes of analysis. A few tags, such as _licensing_ (32%, 35 min), _storage_ (33%, 85 min), and _security_ (39%, 72 min), stand out as particularly well supported, but many more stand out as challenging. Figure 5: Failure Rate and Median Wait Time of most popular techs. Figure 6: Community support for concept Tags. Reference point is based on median values (51% for the Failure Rate, 195 minutes for the Wait Time). Circle sizes indicate the number of questions of the tag. Some tags, such as _controllers_, _combat_, and _leaderboards_, refer to concepts that are specifically about gaming, not merely 2D or 3D design. Among these, _modding_ (66%, 731 min) stands out as the least supported. (Interestingly minecraft-modding (58%, 330 min) is a tag of its own and is the fourth most supported concept per failure rate.) Other weakly supported concepts include _character_ (60%, 187 min) and _multiplayer_ (56%, 179 min). On the other end of the spectrum, questions tagged with concepts such as _savegame_ (43%, 79 min), and _npc_ (35%, 190 min) appear easier to answer. Some other tags explicitly refer to the handling and rendering of 2D or 3D elements that are featured in any typical game. In this category, the tags _video_ (75%, 1682 min) and _blending_ (70%, 517 min) stand out as lacking support in contrast to _side-scroller_ (35%, 140 min), which has the best support. Unsurprisingly, _3D_ (55%, 172 min) is harder than _2D_ (48%, 175 min). The rendering of game scenes and such often requires concepts taken from disciplines such as mathematics and physics. Among the tags that are heavier on mathematics or physics, questions on _rigging_ (76%, 189 min) or _separating-axis-theorem_ (72%, 164 min) are clearly the least supported. Also lacking support are questions on _skeletal-animation_ (66%, 711 min) and _collider_ (63%, 698 min). Other tags of note include _animation_ (60%, 383 min), _physics_ (52%, 290 min), _collision-resolution_ (56%, 464 min), and _collision-detection_ (54%, 270 min). It is worth noting that some of the more purely mathematical concepts seem to have relatively good support: _geometry_ (48%, 150 min), _movement_ (48%, 149 min), _rotation_ (48%, 246 min), and _mathematics_ (45%, 141 min). In particular, _trigonometry_ (36%, 76 min) has one of the highest community support. Finally, some tags are quite generic, whether they come from larger computer/science terminology (e.g., _inheritance_, _bug_, _debugging_) or even broader (technology-related or not) vocabulary (e.g., _art_, _marketing_). According to our data, the least supported tag here is _augmented reality_ (82%, 1887 min); another trending technology that is not well supported yet is_virtual reality_ (69%, 851 min). These are, with _synchronization_ (74%, 307 min), the top 3, by far, least supported tags. Also lacking support are questions about _advertisements_ (63%, 364 min) and _monetization_ (63%, 218 min). Conversely, some related tags such as _copyright_ (59%, 100 min) and _licensing_ (32%, 35 min) show stark differences, with _licensing_ questions being way more supported. Figure 7: Failure Rate and Median Wait Time for most popular concepts. Support for top concept tagsLooking at Figure 7, which features the concepts that command the most attention, we note that most of these tags have a failure rate around 50% (\(\pm\) 10%) and a median wait time from 30 min to 6 h. The tag graphic-effect stands out with a wait time of around 20h. Although many of the most supported concepts (licensing, terminology, publishing, etc.) seem peripheral to game development activities, there is no clear pattern; for instance _monetization_ (63%, 218 min) has a fairly high failure rate compared to more technical tags such as collision-detection (54%, 270 min).
