I perfer old.
Complex =/= better; be it in character development, gameplay, etc. Just because Dragon Age lets you choose from a few different talent trees for each of their classes and you can choose "Asshole; Neutral ; Polite" responses for conversation (that mostly lead to the same thing) doesnt make the game any less terrible. It just tries to cover it up.
My person favorite platform for RPG's was the GBA. It was truely the last game platform that got "it".
Now a days, expecially with Console and PC bound RPG's, the games suffer from one of their most scrutinized points; the Graphics.
Because the Final Fantasy PS1 Era is over, if your going to make an RPG, you will NEED fancy cutscenes. Most characters you see that move in the game will move in a realistic feature, due to the increase for Motion Capture technology. And, if you want to believe it or not, the HUGE ammount of money that goes into making the game look "pretty" kill the funding for the rest of the game. That means all the cool quirks, character options, aching storylines and non-linearity get the axe.
The GBA had the simplest of simple graphics. The machine could render decent-enough models, cheaply. This meant gameplay and characters got to shine. By this point in the business, companies knew what we wanted from RPG's, and delivered them.
RPG's went down hill when Graphics spiked and Western RPG's got too full of themselves *glares at BioWare*[*secretly pats Bethesda on the head*]. This is why I perfer older RPG's.
