Where can I find an idea for a service or software that has never been seen before?

Question

Programming

Hello, tell me where to look for ideas for translating into reality, otherwise it just didn’t occur to me, but Google already found it.
But it can’t beat such that everything has already been done.
To take someone else's idea and improve it as an option, but then what about the rights, they won't take it for an op?
For example, there is one old game for WM 6.5 but not for other platforms, is it possible to take it as a basis and make a clone for iOS and Android, and can it be sold later if the closing code and the game costs about $ 10
Where can I read more about what can be redone, whose projects should be taken as a basis and build on it, and whose projects should not be touched so that it is not deplorable?

Answer 1

Copyright covers specific items, such as images, music, books.
You can also copy names, names, trademarks - everything that uniquely associates your product with the original.
In the rest, though: clone. What 95% of developers/publishers do. I remember Abidas, Adabis, Abadis, Adibas and Abibas.
There are cases when the same games came out under different names due to disagreements between developers and publishers. For example, the game "Star Control 2" was re-released under the name "The Ur-Quan Masters" due to the fact that the Star Control™ brand was owned by a dissenting publisher.

Answer 2

make deep-learning artificial intelligence that can answer medical questions, even legal ones, questions about breakdowns of cars, computers, phones

Answer 3

In a broad sense, very little has been done, in fact. There are more tasks than free hands and the gap is growing. See habrahabr.ru/post/250879
But this is not about games for android for 10 bucks, of course

Answer 4

The plot of the video game is not subject to copyright. And if you do not paste the graphics, but simply redraw them, this is also a completely different work.
Judging by the fact that WM 6.5 was released in 2009 and for 5 years there were no versions for a different platform, then even if it were possible, the authors would not have had money for the trial :)
