There's no hard rule that says that you need to play the previous games to enjoy DD (hell you can technically skip Apollo Justice, despite the fact that DD is a direct sequel) but it's strongly recommended. Ace Attorney has a rich character history, and you'll miss out on tons of contextual callbacks and nods to the previous game. Hell, even the game's very premise (Phoenix Wright returning to the courtroom) is lost on you if didn't play Apollo Justice or the preceding games. That said, the best reason to play the previous Ace Attorney games is because they're phenomenal games in their own right.so I only realized the other day that the new professor Layton is out. I watched the trailer and omg it looks so cool. I have so many questions that need to be answered. I also really want dual destinies, but I've only played the original and justice for all so far. I feel like I must play the others before dual destinies. Is this true? Is there stuff in DD that potentially spoils previous games? Or am I ok just getting DD outright?
