What's the WORST Video Game in Your Collection?

I think it's safe to assume that we all buy video games, other wise, why would we be here? But as we amass our collections every now and a again a game makes it through that isn't up to par. Some how it escapes being traded, sold or passed along to an unexpected "friend". These are the few, the frustrating, the bad. They are proof that not all games are created equal and yet for some reason we can't seem to get rid of them. They are bad games in our collections.

Personally I have more than just one but for the purposes of this thread I'll just choose the most recent thorn in my side, the racing game BLUR. The commercials promised an Adult Mario Kart but what I got was a crappy racer with poor controls and little to no thrills. I almost immeduately wanted to trade it in but it's street value wasn't worth the gas or postage to get rid of it, so now it just sits reminding me of the mistakes of my past...

So allow me to ask, What's the worst video game in your collection?
