I know this question has many individual answers based on opinion but:
What do you think are the Top 3 languages for writing interactive software?

Define "interactive"?

I plan to write a game. So the Application will have to be able to take a lot of input. But now that I think about it I think I just tried to make "game" sound more professional. Also maybe make the thread a bit more general and open.

So I am using c++ to write a game engine right now, but I feel like, since c++ has been around for a while, maybe there is something better? Performance will definitely be an issue, which is why I preferred c++. But maybe there is something in between performance and maintainability. I like c++ because it gives you a lot of control over memory and it seems very "native", but maybe that's just because I haven't tried any other languages yet.

If it's a game use unity or unreal engine. Why do you want to build things from scratch?

I want to know exactly how a game works. Also I was inspired by the Makers of "Teleglitch" and i feel like the best games don't come from pre-made general-purpose engines. I try to keep the graphics simple to save time. Also, to really use the unreal engine or similar, I would have to learn it anyways too. And I don't want to risk the result turning out kinda-satisfiying.
And well, Teleglitch was programmed mainly by one person using c++ and openGL, and then I decided to do it like they did, because there are a lot of things that I liked about how that game "feels".
I know I am kind of expecting too much and underestimating the work I will have to do, but I think that's because I am at that age (18) and i actually really enjoy thinking about graphics, physics, software architecture and math.

Just up front: I am not a game dev, but I will say that C++ is going to be what you want for that. Also it's probably worth it for you to check out a YouTube channel called "hand made hero", it's a guy making a game from scratch, piece by piece, in C++, live on stream and putting the videos up on the YouTube channel. Definitely worth a look for you I think.

Thank you guys! That channel indeed seems very helpful. Also it's nice to hear I am kind of on the right track for a change :)
