for me it was "two worlds",  it was such a buggy game, the worst graphics i have seen this gen on a hd system,the gameplay was very bad/bland,online mode was horrible. i cant see how it sold as much as it did and that a sequel is being made as well.

what about everyone else ?

My worst RPG this gen is also among the best after it got fixed; Gothic 3. It was shit when it released due to the extreme bugs and glitchy performance but its brilliant with the big patches installed.

Yeah probably Two Worlds on 360.
The PC version was good though.

The Last Rebellion

Eternal Sonata just terrible game...

Cross Edge... I still have nightmares with how bad it was

The worst one I've played?

Elder Scrolls IV: Oblivion

But then I haven't played many RPGs and I'm very picky about the RPGs I do play. I pretty much have to KNOW that a RPG will be good before I even slip the disc into the PS3/PC. I'd still say Oblivion is a good game, but it just wasn't for me and there are better games for me to spend my time on.

Most dissapointed RPG was for me Dragon Age Origins. I really could not get into it while I expected so much from it I am really sad about it :(;

The game I really did not like playing was Sacred 2....Also because I could not teleport between those teleport statues and that killed for me the game;

Its between Fallout 3 & White Knight Chronicles

Neither game was "bad" though.

Definitely Fallout 3.

I really hope the new Fallout is nothing like it.
