I think this is my favorite one so far. The historical fiction, "creating and following a character" approach is really a fun hack. We create and follow a character named Marcus as he makes a new friend, all the while using it as a way to experience the world of Ancient Alexandria when the Lighthouse and Library were at their most magnificent.
Gemini is super reliable. Sometimes a bit brief but usually a great conversationalist, especially when it's in the zone. I did have to remind it there were no Ubers in ancient Egypt tho. smh
