Products for the New Old School

James Maliszewski wants to create an Old School product with all the modern production values he can muster. The only problem is, he's not sure what sort of product to make:

Old school gaming isn't stodgy and shouldn't be stodgy. I think I can prove that, but I need the right product to do it. So, suggestions please! If you were to give me an assignment to create the ultimate new old school product, what would it be? What would you want to buy? What do you think would attract the most gamers who might otherwise never give an old school product a chance?
