This is certainly not about what is the "best system," but what you personally find to be the perfect system for you. It's also not to dis on anyone's favorite system, but if you think another would be better based on what they desire, by all means mention it and more importantly why it would be better. So, have you found it? If so, what is it that makes it perfect for you? That is, how does it do what you want in a game? Found one that's close but no cigar? What is it that's missing, what do you want it to do better or different? Or is it great but you want more? Haven't found one? What are you looking for? What game situations do you want it to handle, and how? As this is a design sub-forum, a focus on mechanics and their application would be good. Less relevant is setting details or aids, but certainly rules that bring to life a setting you desire to play in would be relevant. Feel free to share the travels in your quest, unless they be too perilous.
