It was just the right length for me.
I don't play that many video games, so when I do, I take my time with them. With TSOT I really took in all the character dialogue and cutscenes, paying attention to all of the easter eggs and references. I haven't yet completed all of the side-quests so that adds replay value. I'll probably pick it up again and 100% it shortly before the sequel comes out.
