I agree it is hard to pick a favorite. I love all 3 for different reasons, different levels, etc.. I've yet to play the new Doom as I do not have any of the new consoles to be able to play it or a computer that's good enough to run it. Brutal Doom was so much fun to play. I did a playthrough of the entire first episode of Doom 1 a long while back on my youtube channel. Fun times.
