Why do most tile-based indie 2d games look so bad?
In many cases, their walls, grass, trees etc graphic tiles look good enough if taken for themselves. However, what many games seem to lack are a couple of hundreds of extra variation tiles, i.e., they too frequently place the very same, unvaried graphics tile next to each other several times in a row, instead of using different, variated versions for each occurrence (like Teudogar does).
