In the last months, I started to mainly use vector graphics for my game art. In case you don’t know, vector graphics and its standard format SVG are a way of representing graphics by storing mathematical descriptions (like position, size, color etc.) of geometrical objects. Besides common shapes you can also create paths and complex objects with an arbitrary number of edges and curves. By combining the different techniques it’s possible to model almost any object you can imagine.
Tilesets are a wonderful way to create 2D worlds of any size. Back in the 80’s and 90’s, most games used tile-based game worlds because it was the most space-saving approach of creating big levels and disk space was extremely limited at that time (Super Mario World on the SNES had a file size of less than 512 KB). Although nowadays disk space is no more issue at all, tilesets are still popular when building 2D game levels, especially in platformers and top-down RPGs.
