Dead Space vs The Callisto Protocol: So whats the difference?

It's been quite a few years since the last installment in the Dead Space series, and with its remake out next month, it's impossible not to think about the similarities and differences between the original and this spiritual successor. After all, one of the minds behind both projects is the same, and that leads us to similar ideas… and very, very different ones.
