That’s what I assumed was meant when IX was listed as a 'dark' game. For me 'dark' isn't so much an artistic quality, as a plot quality. I don't like lighter hearted games, as it (to me) seems much less epic and heroic if the world isn't in dire straits to begin with. However, making the plot dark doesn't mean the development team should forego all use of color. Games like IX and Chrono Cross are excellent examples of how a colorful game can still have a sinister undertone.
