I'm in a weird minority here. I hate modern JRPGs....and I mean HATE in the strongest way possible and yet I love Dragon Quest. I think most of it stems from the fact that I grew up with Dragon Warriors 1-4 and loved the challenge, the exploration and the simplicity. Unlike some other franchises(such as FF) that have left their NES roots far behind, DQ has kept the formula largely the same and I love them for it. I'm really enjoying DQ9 thusfar and couldn't care less what reviewers say about it.
I'm also a huge fan of turn-based strategy games too, so maybe it's more about having the time to scratch my ass while I make complex, tactical decisions than it is about the type of game.
I swear I love my DS more than any other console since my original NES. There's been so many niche games for it that other developers won't touch with a 10-foot stick(except Atlus, God bless their little hearts).
