I still can't quite put my finger on why GF in 3D worked so well and MI4 didn't. I have to admit that part of it is due to nostalgia (there wasn't exactly a GF franchise for them to eff up). The overall feel of the game, the way it unfolded and the visuals all make the 3D choice seem the natural one whereas MI4 seemed to lower standards and wonder to itself - "Dammit, how can we make this 3D thing work for this game?" [Note: I liked MI4.. just not nearly as much as 1st 3]
