In any event, I have recently added a whole slew of mods to my Oblivion game to see just how far I could push it away from vanilla, so a more rocky-road with a cherry on top. Granted it isn't an easy thing, but I just took inventory of what the game has become and it is a crazy mess that could easily take 400+ hrs to complete. This all being on the same tech that we will see TESV on. At first when Todd had mentioned it was going to be released on current tech, I was a little sad, because of the "wow" factor from TESIII and IV as they were using cutting edge tech at the time of their release. This leads me to wonder if they are going to make a truly amazing game, as it is certainly possible to do so with the current tech...
Well, the improvement from TESIV--->Fallout 3 was quite substantial in the short amount of time they worked to improve the engine. If they had equivalent amount of time for engine development this time around I would imagine we would see some much improved general world textures, view distances, creatures/people, and animations. A decent improvement in each of these areas would make a huge difference to the way the game feels. Hopefully they can tweak the unstable physics and lighting to give even more improvement to the game world.
