I thought that 'Playing God' was about 50% good and 50% bad. I enjoyed the Trill storyline and thought that Arjin was an interesting character. The B-story concerning the micro-universe was abysmal however - which frustrates me because I like high concept sci-fi and I think that the idea of a micro-universe could be the basis of a great episode. This episode also has one of the worst uses of the transporter in the entire franchise. The idea that the transporter could de-materialize then re-materialize something as unimaginably complex as a universe is beyond ridiculous.
