Overrated? Nah OP just playing it on a different time, comparing mechanics then and now is just not right. Back then, their mechanics was considered one of the best in the whole rpg genre. Looking at their story and cutscenes, it's still better than most games now. The protagonist is a female, and the baddies actually win, and that's incredible.
Bet if they make a remake of it with FF7R mechanics, everyone will be salivating. I know I will
