I don't think Dragon Age for consoles would be worth it. I find it one of those games that you should play on PC if you can and not on your console. V:
I have owned Dragon Age for the PS3 (I now own it for the PC), and it wasn't worth playing at all on the PS3. It IS a great game, but there are a few issues that get in the way of being able to enjoy the game. One of which (and the biggest issue) is the frame rate; it's so horrible on the PS3 that it is nearly unplayable. XBox shares some of the same issues, but at least the frame rate on the XBox isn't as bad as PS3's.
