How much time does QA generally take for a big game?Ideally QA is time and a half. For IT. For games? I can't say for sure. Just going by hearsay, I would imagine a year in a 3 year dev cycle. Final polish I would imagine is 6 months. I think Killzone Shadowfall was something like that. They had finished the game 6 months before release it I recall. They spent the rest of the time polishing.
