Game: Baten Kaitos because... everything.
Seriously. I hate everything about that fucking game. The characters are all unlikable twats, the story is beyond retarded and the combat... oh fuck... the combat...
It's like they looked at the standard turn-based JRPG combat and asked themselves "how can we make this more annoying and stupid?"
Also there's a flashback cutscene toward the end of the game where a female character collapses and the most legendarily awful exchange of dialogue follows. It goes something like this:
"Oh, you're bleeding."
"Congratulations!"
There is no water hot enough to wash away that unclean feeling.
Character: Kalas, the main character of said game. Why? Because, quite frankly, he's a ****. And he acts accordingly throughout the entire game.
At one point, he betrays you and it is revealed that he's been working with the bad guys the entire time because he wanted power to kill some douchebag for his epic quest of revenge or some shit like that. After you fight him in a boss fight some time later, he suddenly decides that being evil isn't fun anymore and re-joins your party, going "durr, I'm sorry you guys." AND THEY ALL JUST FUCKING FORGIVE HIM WITHOUT A SECOND THOUGHT. NO. FUCK THAT FUCKING SHIT, I DON'T WANT THAT ANNOYING **** BACK IN MY PARTY. HE TRIED TO FUCKING MURDER YOU, WHY ARE YOU ACTING LIKE IT'S NO BIG DEAL!?
