However, you can still pass ten "stronger enemies" bills the very first time you attempt the story mode, and have a pretty hard time. You could say the disgaea games are as difficult as you want them to be, but that is kind of the case for most RPGs.
After all, even many new RPGs are kind of hard if you don't spend even a single hour at grinding combined through the entirely of the story mode, or don't do any side quests where you get lots of levels.
