How do I determine the draw order of isometric 2D objects occupying multiple tiles?
Here is a solution without resorting to 3D coordinates or splitting your sprite into 1x1 elements, that works if your objects occupy rectangular areas of tiles.
Let ...

In a 2D game with an isometric camera (like Bastion) do I need to create a new animation for every angle the player is facing?
You can always just use 3d models instead of 2d art (3d models don't neccessarily mean a 3d game). Apart from that, not much. You could mirror half of the sprites, but that may interfere with the ...

How to convert 3D coordinates to 2D Isometric Coordinates?
You can represent the transformation between 3D world coordinates to 2D screen coordinates as a projection matrix:
$$\begin{bmatrix}
x\\ y\\ z
\end{bmatrix}
= \begin{bmatrix}
X_x & Y_x & Z_x &...

Is it a good idea to use per pixel collision detection in an isometric game?
The problem with per-pixel collision detection is that 1. it can be very slow and 2. your graphic design can have a lot more impact on your game mechanics than you would like. It is usually better to ...

Are the same number of tiles displayed in an isometric game regardless of phone orientation?
This is a square grid shown using an isometric projection:

How should I set camera in Blender for example to render a sprite which can be used in an isometric map?
