Question about top-down perspective

[JetSetRadioo]

So I use circles that have 1/2 the height compared to the width to establish my angle and keep it consistent. But that's for objects, but I'm making a basketball court and now i'm not sure. Should the ground center circle just be a 1:1 circle or 1:2 circle?

Thanks!

I'm not sure if top-down perspective refers only to games such as Zelda: A Link to the Past, Pokemon, Mother 3, etc. BUT I'd say that it depends on how your squares look like. A circle should be inscribed on a square (fig 2), touching the midpoints of every edge. If it would be a regular square, then it would be a 1:1, if it would be squashed or slanted, then the circle should follow that.
