Here's my object-oriented rendering engine, if you want to make a game that looks like this: https://scratch.mit.edu/projects/327672984/ Here's my tutorial, if you want to do something similar: https://scratch.mit.edu/discuss/topic/298959 This is a 300x50x300 voxel map modeled and baked using custom algorithms in Java, rendered (sort of) isometrically by saving each layer as an image and stamping each image from the bottom up. This is not 2.5D, it is 3D. 2.5D is sort of vague definition-wise, but is generally used to describe games with a mix of 3D and 2D mechanics (3D rendered and 2D world or vice versa). This isn't even a game. Stop calling it 2.5D.
