@bob momento- Umm, what have YOU done? You talk trash like your experienced here. How bout posting some content of your own in your own thread. Be more constructive with your criticisim, or just don't say anything.
@RichMan - Recently we've recived a rash of black corridor pics almost exactly like your own. I'm not judgeing but taking an educated guess that most of these pics are by younger developers, because being scared of the dark is a childs mentality. Add some dramatic lighting to give some life to your levels and screenshots. Seeing something is honestly more scarey than seeing nothing at all. Work with textures to convey a mood. Dingy and dirty give more a feeling of neglect and that evokes an emotion from your players. Total blackness just looks lazy,lol. Hope that was a little more helpful to you.
