I think we should all just chill and let Alex do his thing. He's got to figure out how all of these elements are going to work - by themselves and how they will interact with each other. Giving us notes too early will just lead to disappointment if our favorite feature/detail gets the ax. I would prefer he works things out, codes them up, and then does a bit of testing on his own before he reveals what are going to be game defining decisions. I'm sure he will consider our feedback when the new features hit our screens, he always has.
