I'm not sure that using the entire QA staff of the world's largest agglomeration of Dev studios on a single game only qualifies as "not cutting corners". That's surely going above and beyond.
If that's what it takes to ship a game that doesn't have multitudes of game breaking bugs like they're known for, perhaps the company has bigger problems. Like still using an engine that is this bad.
I really don’t like the word agile since everyone I ever met who had this in their job title was blowing up steam someones butt. Is that the job description or what is it with these agile types?
Agile used to refer to a very specific way of developing software, but then it got coopted by the mainstream where companies kept doing shit the same way they always had but calling it "agile". It's basically like when early Christianity became the state religion of the Roman Empire.
