My opinion: Halo 3 was the worst game ever. Most hyped and it was rubbish.

The Elder Scrolls III: Morrowind

Black & White was absolutely terrible. Five levels and it was such a let down. I played the game for maybe 4 hours before I wanted nothing to do with it.

Morrowind is up there too. It had no direction and seemed to do little to really draw you in.

Agreed. That game sucks even more if you play it for the first time after being impressed with Oblivion.

NBA Courtside something for the N64. Sooooo boring...

Really probably things I had on my Jaguar, as I didn't buy or pick it out, I buy good games, so I don't play many bad games.

Batman: Dark Tomorrow.
I got it free with a Wii game at Gamestop.
The camera is placed in fixed positions ala Resident Evil, and as you move through the world it will suddenly snap to a new shot. This happens almost randomly, presumably to give the game a cinematic feel, though all it usually does is totally ruin your ability to control Batman.
Here's the deal: you're pushing Up to run 'up' away from the screen, then the camera jolts to a new perspective, perhaps a 3/4 view from the left, at which point you're suddenly moving to the left even though you are clearly holding Up on the stick. You have to stop moving completely so that the game can figure out that Up should mean up, not left, at which point pressing Up now sends you up.
So, let's say you then press Left to head to the left (which you were previously doing by pressing Up, remember?) and exit the screen. The camera now spasms its way to yet another angle, perhaps now to a classic third-person behind view. You're pressing Left but you are now moving Up. So once again, you stop moving entirely, let the game recognize the fault, and then it settles down again.
What this all means is that you're constantly going the wrong way. Confused? Just try playing it. Or better yet, don't play it and just take my word for it. It's the most aggravating thing ever.
The start of the game is terrible: you find yourself standing at the top of a building at night. You then have to use your Batcable to swing to another building, which is only clear thanks to a green glow on your small radar map. So off you go, swinging and landing and oftentimes dying just trying to hop from building to building with no fights. That goes on for about 20 minutes.
I played it only one time and i don't want play it again anymore
Gamerevolution gave it a "0/100" lol!

Sonic the Hedgehog for the Playstation 3 is the worst game I have ever played. I do not think it is the worst game of all time. Strawberry Shortcake for the Atari 2600, would probably be it. I don't even know if you could classify it as a game.

Worst game i have played this generation is Def jam icon on the PS3, it was a total let down after the good PS2 games. The worst game ever would be Nightmare creatures on the N64. SMG was also a big letdown for me.

Oblivion is pretty high on the list of worst games I've ever played. Also the Black & White games. If everyone hadn't said they were so good before I played them I might not consider them the absolute worst, but as it stands Oblivion is probably the worst experience I've had with gaming.
