From the sounds of it, the PC version of Dragon Age: Origins won't have any exclusive content (with the exception of the PC mod tools) compared to the console version. However there does seem to be one interesting feature that is unique to the PC port of BioWare's fantasy RPG.

You may remember that Dragon Age: Origins is supposed to be the spiritual successor to one of BioWare's earlier games Baldur's Gate. That game had a top down perspective while playing the game. Well, according to Kotaku that kind of perspective remains in the PC version of Dragon Age: Origins. The console ports don't have that option at all; their gameplay viewpoint is stuck in a behind-the-back action pose. So if you want a more tactical-strategic look for the game, you have to play the PC version. Cool.
