I had this on the old Xbox just before the 360 came out. Is it really worth getting again? The graphics weren't all that bad on the Xbox. What can they possibly have done with the graphics in the intervening six years - totally new in High Definition with 3D, or merely upscaled to 720p (pseudo HD)?
I never had the original two games, so that might tempt me. But otherwise - I think I may pass on this one. Depends on the price. If it's low enough, I might conserider it.
What is the online multiplayer like? That was quite good on the Xbox. If it's now on PSN then that would certainly be a point in its favour.
