Hi there.

So for the past year and a half, I've been developing increasingly complex projects using the Twine/SugarCube development platform with the heavy use of JavaScript. However, I've started to find myself missing some of the more advanced features of a full programming language such as C# (e.g. interfaces and out parameters). I've been looking into ASP.NET as it seems to be an interface between C# and browser-based technologies, but I find myself having a very hard time parsing the tutorials/documentation. The primary focus of ASP.NET seems to be working with a backend server and databases, and that's way more than I need and a bit beyond my current level.

What I want is to create the “engine” of the game in a language such as C#, then use HTML/CSS/JavaScript to actually create the user experience, but I don't want a backend server involved in it. I'd like it all to run as a stand-alone application on an individual's computer, preferably not even requiring an Internet connection. I'm getting the sense that this is a very niche aim, but perhaps I'm not looking in the right places?

Could anyone give me a little direction/make some suggestions? And in case you are wondering why I'm so set on a browser-based UI, it's due to accessibility concerns. I'm blind and I know how to make webpages usable by myself and other people with disabilities. So far, every other game development engine I've come across relies very heavily on a GUI and strictly graphical components, which not only makes them impossible for me to use, but would make the game impossible to test/play.

@SyncViews I've come across mentions of some of those you listed, though I've never gotten a good answer as to what they are or what they are for. I'll look into them again now that you've given me a more narrowed list (there's so much out there). My main worry is that developing a large game with a lot of data and procedural generation in a scripting language might end up being very inefficient and would run very sluggishly, but that's just an assumption on my part.

As to ASP.NET, it really does look like what I'm specifically asking for here, but could anyone point me to some tutorials or teaching tools that are less… verbose than those on Microsoft Docs? Those and the tutorial on TutorialsTeacher pack so many specialized words into a definition, often using terms to define themselves, that I find myself unable to parse a lot of what is being explained. I have a basic idea of what it is and how it's meant to work, but actually making any use of it is beyond me at the moment. I'm sure I could get a handle on it as i have other languages; I just need something less dense to learn from.

Yes, the capabilities of each browser and version are always a challenge when developing anything for the web, but at the moment it really is the platform I know best and the most accessible to a screen reader. I suppose what I mainly want is a way to take some of the burden off runtime processes. Using just JavaScript means that the game basically has to rebuild itself every time it's opened or even every time a page is refreshed. But, as I said, I'm not familiar with Electron or the other technologies you mentioned, so I'll look into those and see if I can't wrap my head around what I need. (Being self-taught means I usually need to find explanations to explain explanations to explain explanations. lol)

@SyncViews I've only just started looking into it, but it does look like Electron might be a really good option. I'll need to learn Node.js first as it uses a lot of the same script, but so far that hasn't been too bad. Thanks a lot for your help. :D
