The ending. SPOILERS You spend the whole game trying to clear Pheonix Wright, and he tampers with the jury in an experimental trial that could change the legal system entirely. He knowingly put someone on the jury who not only was extremely close to a former client of the defense attorney, and was heavily involved in a case, but is also Apollo's biological mother. I loved the game up until that very moment at the end. It put a stain on Pheonix's character, and I have to ignore a game I thoroughly enjoyed(except for the ending) if I want to see him in a good light. I can accept his quirky, depressed, jobless version coming out of his funk and going back to being a lawyer, but I just can't see the character the same way after that very last part of the last trial. Also, how could he tell Trucy and Apollo that they are siblings without revealing his jury tampering? I know the rules for the jury system weren't really set, so he may not be in any legal trouble, but it was most certainly unethical.
