(Low Quality Comment Here) I, for one, have never had a tumble in KSP. Nope, every single launch, exactly as planned, all the way to orbit, and even the Mun. I have never once strapped a bazzilion first-stage engines in a row just to see what happens. Never once stacked them as high as I can. Nope - totally responsible game player over here.

Note: Trying to fly Jeb directly into the Sun was a real lesson in Angular Momentum.
