After this discussion here, I noticed that the dislike of some biomes really is down to their sometimes muddy and indistinct graphics, something that that led Cousken to create the Visually Distinct Biomes mods. On the other hand, lots of people really like Primordial "out of the box" because it has strong contrasts and succeeds at conveying its theme. After some thinking and a few experiments, I started to tinker with the colour schemes and textures of the original biomes, trying to achieve nice distinct themes and colours like Primoridal has but make them as readable as Cousken's mods without sacrificing the themes (e.g. his version of arid is a lot more playable and looks rather nice, but the grassland feels too fertile and too nice to me). Here is my first WIP for the arid biome (warning, big-ish pictures): Spoiler Arid WIP : The themes and "atmosphere" I want to evoke with this are that of a dry, ancient and dusty world - with the deserts evoking Arrakis, Tatooine and a little bit Mars, the plains evoking Mars or Arizona and the grassland evoking hot and dry African steppes. Opinions and suggestions? Should I continue?
