Blender or OGRE

I’ve been working with Blender for upwards of two years now and despite looking at endless tutorials and articles on the BGE I have yet to start any projects with it. Therefore I have decided to start one but I would first like to know: if I was lookin to make a game with the Elder Scrolls III: Morrowing type graphics would the BGE suffice or would I need to use either CrystalSpace or OGRE and other libraries.
Feedback much appreciated.

The BGE doesn’t really support a lot of the fancy tricks you’re accustomed to in $$$ games. That said, it can still look mighty fine with good textures and shading.
