Still a little premature as it's not out yet, but between The Witcher 3 and now this seeing CD Projeckt Red so far ahead of the rest of the competition makes me wonder what their work environment and staff is like. Their cost of development is low in large thanks to being situated in Poland and not having to pay employees as much, but they have to have a large crack team of vets to pull this stuff off. So to keep everyone on board I wouldn't be surprised if those same employees also got generous bonus packages, aren't constantly kept in a meat grinder, and are given a degree of creative freedom to find the work rewarding.
Whatever they have going for the rest of us it's a damn shame the model can't be replicated more, in place of the big publishers we do have in North America that with the size of the budgets they get look like a joke in comparison.
