I was curious how this worked without violating the copyright of the originals. I was imagining something akin to tracing over the original game assets and calling it a libre replacement, but it seems like they actually did it in a reasonable way: >New art is being drawn in the style of the original game, using the original 8bpp palette. The graphics should be a similar but distinct version of the object in question - no graphics may be copied at all from the original. The new sprites do not have to be the same size as the original, but need to be similar so as to fit into the game as expected. https://wiki.openttd.org/en/Archive/Community/Graphics%20Replacement#artwork https://wiki.openttd.org/en/Archive/Community/Graphics%20Rep...
