Spectral Force 3 - the worst RPG I've played this gen

Eternal Sonata - pretty looking game, but boring as hell story

Infinite Undiscovery - another poorly made RPG with laughable characters and some of the worst voice-acting I've ever heard in a game

Rogue Warrior. I bought it because I like the books, the game is like a lesson in how to do everything wrong.

Soldier of Fortune Payback, about an hour of that game was all I could stomach... thankfully I had only payed 10 bucks for it and it came with a copy of First Blood so it wasnt as bad as it could have been.

Rented FEAR2 and really could not get into it.
Returned it after playing the game for 3 hours...

a game doesnt have to be bad for me not to finish. i just lose interest sometimes and move on to other games.

Unlimited Saga

Biggest one for me this generation (and the only one I can think of...) is MadWorld. Played the first level and that was all I needed to know that this was going to be one repetitive game. Also, its violence shtick is something that doesn't mesh well with me.

Plenty, but it depends on what you mean by that. I mean, I've never completed some games based on bad AI, crippling difficulty or even plain annoying gameplay.

I think the game that best solidifies what I think you're pointing at is Rogue Squadron III: Rebel Strike. The space missions were dumbed down to a point where all you had to do was shoot things coming straight at you. And then they inserted now 'land based missions' that amounted to nothing but running around with some of the most horribly animated characters shooting blasters on foot. And most of the time, you couldn't even shoot anything. Think Star Fox Assault with narrow canyons and not being able to aim your puny blaster at any enemies.

This game:

Just horrible!!

Ill second this one.
