### Tech Tags: Technology/Library Choices  
Looking at the tech tags in Table 2, we observe that, with respect to the number of questions, the game engine _Unity_ is, with 9029 questions, the top tag by far, followed by the programming language 'C# (4212 questions), which is unsurprising, since it is the language of choice for _Unity_. Aside from _Unity_, frameworks and technologies such as the API for high performance graphics _OpenGL_ ([[https://www.OpenGL.org/](https://www.OpenGL.org/)]([https://www.OpenGL.org/](https://www.OpenGL.org/)) (accessed on 1 October 2021)), the game development framework _libGDX_ ([[https://libgdx.badlogicgames.com/](https://libgdx.badlogicgames.com/)]([https://libgdx.badlogicgames.com/](https://libgdx.badlogicgames.com/)) (accessed on 1 October 2021)), Microsoft's game framework _XNA_, and the platform _Android_ generate the most questions. Aside from C#, languages such as C++, _Java_, and, to a lesser extent, _Javascript_ lead for the number of questions. A ranking by average number of views presents a very different picture, with _Unity_ barely making it into the top 10 (1202 views on average) while a narrower aspect of it, _UnityScript_, its now deprecated scripting language, is ranked seventh (1436 views on average). It should be noted that, although the average number of views is not correlated with the number of questions, 8 out of 10 of the top tags per average number of views have under 100 questions. We used average as a metric aggregate, following [17; 24] in that regard, but high averages could be the result of one or two exceptionally popular questions. For instance, the top tech in this category is _Vulkan_, a _\"low-level, cross-platform graphics API\"_; \begin{table}
