How to make a site “like in video games”?

Question

Programming languages

Hello.
An idea came up to implement it - you need to make such a site:
The main window with content is a kind of map of the area, for example, as in The Witcher 3. You can scroll the scale, select objects by clicking, view their descriptions, and so on. like in the game.
And so, the main problem that I do not represent on what it can be implemented. I thought as an option to consider Unity, HTML5, FLASH. But suddenly there are some tools more sharpened for this business? Considering that I will do everything myself, in my free time, it would be useful to be easy to learn.
Thanks in advance for pointing me in the right direction.

Answer 2

You can use Phaser
The examples have a whole section for working with such cards (just for your task)

Answer 3

What's wrong with Unity? There is a terrain editor, write scripts, and there are plenty of third-party plugins. Although if it is a purely browser-based project, then I advise you to turn to webgl-engines. Something has already been suggested to you. Blend4Web is also promising. As an example, the developers themselves made a large-scale game on it . All sources are open, so you can dig deeper.

Answer 4

Если говорить именно о карте, то можно попробовать такой вариант – использовать Google Maps API + кастомные тайлы.
