GOTY? So far a resounding YES!
Best game I've ever played? No, but it would make my top 20 for sure, maybe even my top 10, I'd need to think about it.
As with others I'm not sure what you mean by revolutionary. It's highly polished and you could argue that it sets new standards for script, pacing and the cohesiveness between gameplay and story. Despite that it doesn't really do anything new or innovative it just raises the bar in certain areas.
