Classic 2D arcade platformers, brawlers and beat 'em ups can have amazing background art—with pixel perfect details and a wonderful color palette. Unlike the similarly awesome 2D fighter backgrounds, people don't pay as much attention to these. Looking through 2D arcade game backgrounds, it's funny to see how the artists were so into dodgy city districts that are so characteristic to the 90s. But for me, the best part is finding the small details—whether it's an easter egg or a hidden tiny item.
