That suit alone looks like it'd cost thousands of dollars to make, and then adding in all of the steampunk props and complex atmosphere with the splicers and dilapidated surroundings. It'd be like the Silent Hill movies, but calling for a bit more to get right. With the Silent Hill movies, you could easily use CGI for a lot of things with how supernatural everything was, but aside from the water outside, splicers and plasmid effects I don't see what else CGI could fit well into such a dark yet more real world without looking overused.
But god the amount of effort to make such a world would be worth it. Thinking about it gives me chills.
