What's the worst video game you've ever played?

I remember buying Duke Nukem Forever in a Humble Bundle, a bundle that I had virtually every other game for the price. I remember only paying $1 and I gave *all* that money to charity.

I played DNF. I still felt robbed. To this day I haven't completed it due to how terrible it is (if my memory serves me, I've been minaturised and I'm driving around in a tiny car? But the controls are awful and Duke now seems like a Trump like character whose charm is entirely devoid in modern times. It was already wearing thin back when it was released, too).
