It can be any game past or present and cover art would be appreciated. If you want you can say why it's so horrible.

I would have to say it's Sonic the Hedgehog. Not the Sega Genesis/Mega Drive original. The one for PS3 & Xbox360 it' one of the few games I couldn't bring myself finish even after owning it for years. The controls and camera are terrible the visuals for some reason always gave me a headache and the storyline was strange to say the least. So if you do by some chance happen to see this game don't waste your time or money.

I can at least say Sonic 4 looks very promising.

Dead to Rights the latest one, it was so bad, it made John Woo's game look like action game of the year. 

Kingdom Hearts: Chain of Memories. Have you ever tried to drive while looking at a map? Your chance is right there!

The sword fighting parts in Red Steel 1

Dark Void.

star ocean 3 for ps2, or at least parts of it.  the storyline was good, but the battle system was so clunky and glitchy.  and the experience curve for the monsters you fought was very lopsided.

Trinity universe was boring as hell.

Final Fantasy VIII.

Ugh, let's see. I've been quite lucky so far this gen but a few games comes to mind. I can't remember in which order I played them though...

MadWorld was fun for 5 minutes. Atleast I forced myself into thinking it was fun. After that it was just repetition, repetition...Even though the game is supershort I couldn't finish more than maybe 30-40% of it. Went into my pile of "Played but not to be played again"-games.

I also tried Heavy Rain. I soon realised that the tank controls (it's 2010 damnit!) and awful amount of QTE's made it unplayable for me.
