[@Peridot] I agree, I like to see immersion in writing that activates my brain with sensory information. It's important for both visualization and holding interest. However, I'm not sure it's something I'd expect or ask for in low casual or free. (Though I'd have a big smile if I saw players doing it.) Above casual maybe but only to a certain extent. Wouldn't ask players to have novelist tier skills.

That being said, there are times when it's okay to tell instead of show. When summarizing, moving time, avoiding repetition, and simply to avoid uber-description. There's moments it is appropriate to narrow in and describe in detail and others where you want to keep things moving. Sometimes these moments occur back to back with each other, even sentence to sentence. One sentence is full of evoking details, the next gets things moving and is brief. During these moments of moving along, it is possible to "tell" in an entertaining way.
