I am the target audience for this game as both a huge tactics and strategy game fan as well as a massive Persona fan. I actually do like the art style for this game - it took some time to grow on me, but now I do really appreciate the cartoony appearance. I do wish more unique art appeared in-game, as the same images are reused constantly. The voice acting is quite good in both English and Japanese. The writing is another story altogether. Maybe I'm just getting a bit tired of the Phantom Thieves, but these versions of the characters were nearly insufferable and reduced to flat, flanderized versions of their original characters.
The tactics gameplay is good, but far too easy. I especially enjoyed the Quests and Challenges - these served more as puzzles than as typical tactics challenges and required you to use the mechanics of the battles to achieve other objectives, or to use them in the most efficient way possible. Otherwise, almost all of the missions are "Defeat all enemies" challenges and, while the battlefields and mechanics are fun and interesting, does get a bit stale after a while.
The Persona/SMT elements are well-represented here. Persona fusion is important and just as strategic in the mainline games, adding a bit more to the tactics gameplay. However, this game is definitely a tactics game for Persona fans, especially Persona 5 fans, rather than a Persona game for tactics fans.
