What things are a part of your ideal session, other than the actual game?
I prefer to sit at a table with a good chair, but one that will also let me stand up a lot; so one that won't knock over or not slide easily. I like to have a lot of really sharp pencils, plenty of paper to write notes and of course something to drink. Not alcohol, I learned a long time ago that drinking and D&D don't mix with me, but something to keep my throat from getting dry. It used to be Mt. Dew, but these days it is more likely to be water or tea. And plenty of light.
One of the things I am happiest about is to be at a point in my life to be able to afford the game room of my dreams. I have shelves where all my books are easy to get to, I have a nice table and cool art on the walls. Plus my kids my love it and I often find my son down there just working on characters or adventures.
I also love having people are that there to play. I don't mind table talk or the inevitable Monty Python quote storm; that's all part of the game really.
