What is the best way to Build on Perfection. Every once in a while we get something that simply feels like it is the best it can possibly be. Leaving little to no room for improvement or expansion. But low and behold.... the creators decide to build on it. Some examples of things I would consider Perfect and yet are being expanded or followed up on: Call of Duty 4: Modern Warfare ------> Call of Duty 6: Modern Warfare 2 Halo 3 ---------> Halo 4 Crank ----------> Crank 2: High Voltage and there are definitely other things out there. So what do you think the best way to Build on Perfection is? Build on the Design? Do you do something New?
