As one can verify from their video, the mechanics and tactics show a great deal of inspiration from Thief, as is the case with the intense and unearthly mood. Yet, whereas Thief seemed to draw its core from steampunk, symbolist artwork, and perhaps various authors from Weird Tales, Tangiers seems firmly enmeshed within surrealism, as per the references to Burroughs, Ballard, Dali, and Lynch. That is, it will be if they are able to amass the necessary funding at all. I for one am very intrigued by what this very small group of computer-based artists are attempting to do, and would love for their endeavors to see the light of day. Or at least the strange light of day as perceived under a solar eclipse or the aurora borealis.
