Which games did you drop because they were too difficult for you? I'll start.

Despite playing Persona Q on the second easiest difficulty and Devil Survivor on the easiest, I was stuck in a constant loop of:

Getting my ass kicked ➡️ Grinding ➡️ Progressing and repeating

Looking back, I understand why I struggled with Persona Q, since I hadn't played other games of this style or other Persona games besides Persona 3 Portable. But with Devil Survivor, I'm surprised it gave me so much trouble, despite being a fan of tactical games and having played other games of the main SMT series.
