Fun little story, but didn't really stick to my ribs. The characters were fun, but the ideas didn't seem to fresh. Isn't the idea of super intelligent beings playing games with humans out of boredom the plot of like half of the Star Trek OS episodes?
Minor gripes:
-Is anyone else tired of AIs in fiction just waking up one day? There are more interesting ways to create an AI.
-If Sarisvati made the water spirit (which I think she did) and the ghosts to challenge herself or Pradesh (thanks, TAD), then she chose Edgar and Raven to play, too. But with every human being in the world to chose from, why pick these dopes? They don't seem particularly stimulating as players or opponents.
