Sometimes. Whilst, I like to be entertained whilst reading sometimes dry rules, sidebars sometimes leave wanting more without any recourse. What I am a big fan of, is those RPGs that have a story segment at the beginning of the sourcebook/chapter that evokes the atmosphere that rules are meant to capture. But, then again, I would be happy with sourcebooks that were rules lite and tend to be a storyteller in my games, anyhow.
What I found most interesting was when I mounted that poll, so many others fell into the same camp. So, maybe, it is the future to adopt more storytelling techniques.
