Look at the rise of Dwarf Fortress leading to Minecraft and its various imitators. Once you get to the polished, simplified level of Minecraft then it can be (and has been) ported to consoles and phones, but the experience doesn't start that polished. You need to be able to experiment with something clunkier, something with many more possibilities - and something like Dwarf Fortress couldn't possibly happen on anything other than the PC.

I think, anyway. Maybe that's got nothing to do with it, and we see innovation on the PC solely because it's a more indie-friendly development environment. But I think it's telling that the dev versions of consoles come with keyboards.
