Gears of War or Halo

I dont remember the worst one, but the most disappointing game that i remember is Lego City Undercover 3DS.
After the really good Wii U version my expectations were way to high. The render distance was awful, the gameplay was bad and it was no fun at all.

Deadly Premonition

Damn. I really want to try that game because I've heard it's packed with Twin Peaks references. 

Anyone play that Universal Studios game on Gamecube? That was pretty bad

I've played some serious shit in my life, and based just on personal bias and just how devastatingly disappointing I was in it, I'm sorely tempted to say Star Fox: Assault. That game was a depressing, insulting slap in the face for a guy who loves the shit out of SF64 and was SO hyped for what I hoped was going to be a genuine, quality sequel. It's like expecting a fancy steak, and instead getting a half-eaten AM/PM burger.

BUT, sadly, while I hate the fuck out of that game and it deserves such a label, it is not in fact the worst game I've ever played. Something like Action 52 could certainly count, but on the other hand it really doesn't count, because nothing on that cart was enough of a full GAME to be considered shitty. So.....I would honestly have to say that while there are many strong contenders (Superman 64, etc.), I'm going to have to go with Defenders of Dynatron City on NES. Even as a kid, a kid who was far more patient with games and managed to see silver linings and glean enjoyment from most games I rented, even if they weren't very good, even with THAT childhood mindset, when I rented DoDC, I only managed to play it for about an hour before I had to admit to myself that the game was a practically unplayable, steaming pile of trash, and turned it off, never to touch it again.

Motionsports for the 360 kinect.

I nominate Chronicles of the Sword for PSone. At the time I had only just started working after leaving school and was earning peanuts, saw this game pre-owned in a shop, traded my game in and paid the rest and rushed home to play it... I barely made it past the intro :( at the time I wanted a new RPG after just finishing FF7 and Suikoden and having the best time.

Ultraman: Towards the Future

This is what it's like playing:
