I just asked this question a bit ago, but it was mysteriously deleted. Not sure if anyone answered, as I didn't get to checkIs it a bad idea to read for answers. Anyways...
I have read on numerous answers here on StackExchange that Mapsuse a map data structure (the container) are "horrendous", "bad", or "awful" in game design. Yet although multiple people have stated it, no one has explained why. I'd also like to hear from others, because I am skeptical as to whetheran associative array or not they are "horrendous"dictionary) in game design.development?
According to this popular mapflowchart, the answer to GameObjectideal container for storing game object's container would actually be a 'map'map for many games, yet I have repeatedly read (only on StackExchange). But I've heard anecdotal claims that maps are horrible ideasa very bad choice for GO containersgames.

Is this true? Is there rarely an instance to use a map? Are Maps bad enough on performance to justify them being "horrendous" for game design?
Why?
