Isn’t it a bit… selfish for you to expect everyone everywhere know your fucking context? 88 means shit nothing in Europe and we’ve got the original Nazis here (except of course if you’re Nazi - they know about 88, common people don’t).

The heck you’re talking about? There’s a ton of free resources to learn the basics.
https://dotnet.microsoft.com/en-us/learn/csharp official Microsoft learning resources.
https://dotnettutorials.net/course/csharp-dot-net-tutorials/ for C# basics and .NET framework (which is backend standard).
For game engines you need specific tutorials in those engines.

In general, untill you have terabytes of data or a significant amount of traffic (operations per second) database choice does not matter and you should be using cheaper option, where the cost should be assessed as a derivative of price of hosting, cost per operation, cost to deliver (how familiar you are with it).
When you have significant amount of data or traffic - only then you should worry about database kind or language. Until then this could be a premature optimization.
