This section will include added notes and other topics that don't quite fit in our Unity project for a number of reasons; topics such as Virtual Reality (VR) for a side-scrolling game that could work, but ideally would be better suited to a first-person view format to help with the potential issues that a developer may encounter.

Other topics, such as Unity's networking setup, are somewhat ill-timed as regards the Unity programmer exam as this topic is marked as deprecated and Unity is currently working on a new networking setup as of the time of writing this book. I, therefore, thought that this would be of greater benefit as general knowledge.

Finally, in the last topic, we will cover some random general knowledge pertaining to Unity that could also help you through the exam.
