To think that someone making a game, and not doing it the way you believe they should, is a personal affront - is just madness.
I'm sorry to break it to you, but that's exactly what happens in big companies like Eidos. Zero creative freedom, doing overtime - all the time, shitty salary, people fired after project completion and so on. Don't believe me? Just poke around some developer/modding communities and ask some people who had the chance to work at big companies. They don't do what they want to, they do what they're told to, which often contradicts with their vision and creative sense. That's why you see a lot of kickstarter project from professionals that come from big companies. I agree that people at Eidos aren't retards, many of them probably wanted to create a "true" thief game, but it doesn't work like that. What the developers want and need are not Eidos (as a company) concerns. Many "computer savvy" people (as in programmers, people who can do 2d and 3d art etc) consider working in a big development studio the worst career choice possible. Sad but true.
