Well, there's a number of playthroughs of Q on youtube and the only person can think of off the top of my head is omegarevolution's playthrough if you don't mind something along the lines of a completionist run. The only problem is it's difficult to find his videos in order of beginning to end. Here's one that I'm pretty sure doesn't have commentary.

Is there anything about the spoilers that could occur that you wanted to talk about?
