JRPG is perhaps my favourite genre.
These are my reasons.
A game NEEDS strategy. Nothing comes close to JRPGs in strategy.
Games need awesome music. That sets mood, and mood is very important to me. JRPGs usually skip having some stupid singer sing, and I prefer music with rhytm.
Story. Games with a bad story need to be awesome to be good. Being a great game is next to impossible, for me, no other company than Nintendo has done that. The way they do that, is by not focusing on story. If you focus on story, it has to rock. Nothing beats JRPGs on story.
Character design. You have to like the character, get into the role character, or have a totally weird character. It has to be one of those, and preferably, all the roles should be taken by different characters. JRPGs have the best character design.
A reason to fight, both for you and your character. Why do you have to kill that guy? And no, just because he's there isn't enough. You also need a reason for yourself to fight, such as leveling. Without that, repetiveness gets even worse.
