Well..... There is value in actually playing the games with social links, fusion, and combat and stuff but the story is what drives it home for me personally. If you don't find the other aspects of the game interesting then I don't think you'll enjoy yourself with the games. If you want a substitute then maybe look into devil survivor.
Not a bad game I prefer the mainline persona series. But if you crank up the difficulty on q it is one of the most unforgiving games I've played. And let's be honest the only reason I play the megami tensei series is for the absurd learning curve
