These are free to use tile primitives for any 2.5D Oblique View game you are developing. These are the basis of the tile system for Epica Rex ([link])
Tiles here are aligned to a grid of 96 pixels wide, and 96 pixels high and have a 64x64 pixel footprint base.
Keep in mind, that these are just the shaded primitives. It's up to you to edit them and make them look pretty for your game or pixel art scene. I may include an isometric primitives set if people seem to dig this.
