The fact of the matter is that the vast majority of console games are designed to be easy to get into, with a short learning curve and a lack of depth and complexity (I'm not saying this is neccesarily a bad thing, I like a mindless shooter or a driving game as much as the next guy too).
My only real ray of hope is that bioshock (a very in-depth and complex RPG by console standards) was well recieved on all platforms. If other developers take note and attempt to follow suit, things could look up for DX3 and similar games. I aint holding my breath though.
