Adding one more to the Ace Attorney spinoff block:

Tyrion Cuthbert: Attorney of the Arcane is a well-written fan spinoff of the AA formula, taking place in a fantasy universe where magic is real, but mostly the domain of the nobility. Trials are a form of theatre, where the nobility knows how to tip the scale, but your mentor knows how to tip them back.

It introduces some very enjoyable mechanics, in which knowledge of each spell's effects and conditions constitutes its own evidence. Tyrion bears his own magical ability that lets him view the thoughts of witnesses. He is also accompanied by the defendant of his first case, a mercenary-mage named Celeste, who gets a lot of investigation banter with Tyrion, much like Maya and Phoenix.

Five cases in all, and none of them are shortened crapshoot cases, nor is there a downer ending; all the major threads conclude with satisfying endings, and the developer hopes to make a sequel from the world they've built.

Oh, and as is common for AA games, take a listen to "Eye of Horus", the game's equivalent of the "Objection!" theme when Tyrion nails a contradiction. The game's soundtrack as a whole has some real bangers, for both the high points and the emotional pulls.
