At heart, this is still the Ace Attorney you know and love: examining testimony and getting criminals to break. Honestly, I wish the game would've put more of an emphasis on exploring the environments. As soon as you enter the room you're supposed to be in, the game will typically lock you into that room. I did enjoy the "Logic" system, which was really intuitive, and I thought the "Little Thief" was an interesting idea. The story can get a bit convoluted at times, but I was rarely stuck to the point of looking up a walkthrough.

TBH, you probably don't have to play this game before moving on in the main series, but I'd recommend it if you want a quick change of pace before moving on to 'Apollo Justice,' as 'Investigations' seems to take place before 'Apollo Justice.'
