So one of the major cake mix companies spent millions of dollars developing a no-mix no-stir cake mix product that, though a great product, ended up being a terrible failure largely because buyers of the mix felt like they weren't doing enough work.<p>Even though this may be an apocryphal story (I can't find a link on Google), I think it illustrates an important point about user experience. As someone who has played tabletop games, physically rolling dice was an integral part of the game because it was, to romanticize it, the closest physical analogue I was going to get to actually slaying that diamond spider. Pulling out an iPhone to roll dice doesn't have that same appeal, and in addition, you are trying to supplant a long-standing ritual that is inextricably associated with tabletop games.<p>This is, of course, merely a possibility to consider. Personally, I would talk to more customers, if you haven't, or even test them out at local gaming nights and see what people are reacting too. See what other products gamers and DMs need -- after all there are over 20 million of them out there for D&D alone according to Wiki, which is a big enough market to make money out of. Maybe DMs would like a way to manage characters or stats, for example. Build a brand out of related, high-quality products in the process.
