Dave3d: Ummmmm.
What?
There were parts in EVERY CD TR game that was almost impossible to get past if you didnt have a controller.
As a matter of fact, I never finished any of the 3 because of this fact. Although the first 2 didnt have as many as the last one did.
Strange. From my experience the main thing CD TR games were missing was the difficulty :P. I haven't witnessed any places that were "almost impossible" - I had problems finding places that were remotely challenging (in this regard at least Anniversary was a noticeable improvement). The controls were perfectly fine - the only exception was jumping during wall-runs in Anniversary.
I'll admit that camera did have it's problems.
But again - I can't say anything about Underworld because I haven't played it.
Dave3d: At least core did a darn good job of porting over so the m/k actually did not hinder gameplay.
And it doesn't hinder gameplay in CD's games either. They have learnt their lessons after Defiance :P.
