I'm gonna try to keep this as short and vague as I can because if you're reading this you should play Investigations 2 as soon as you can!

Experiencing everything blind is the best way to go for this. If you've liked an ace attorney game you will probably get a lot of it. I would recommend playing through the original trilogy and investigations 1 to have full context of the characters.

I'm not sure if this is my favorite ace attorney game yet, but it's definitely my favorite story of any of the games I've played in the series so far and you should find a way to experience it yourself!
