I would like to have The Elder Scrolls IV remade and remastered regarding graphics and gameplay.
There are obvious flaws in character appearance, dialogue, combat, etc. in Oblivion that they improved in Skyrim. In my opinion, Skyrim's gameplay is better, but the world is not one I can get into...
Oblivion's terrain is perfect to me - even though people say it was "too green and the same thing all around." In Cyrodiil, you can actually get LOST in the wilderness. In Skyrim, you're constantly crossing paths with roads... and glitches. Skyrim does not seem to have the addictive element of Oblivion in regard to the fact that I can get lost and emersed in the world of Oblivion. In my opinion, I think Oblivion has the best storyline and setting over Skyrim. Dragons are badass in Skyrim, but remade Oblivion gates with legit warefare and non-annoying Daedra would overpower Skyrim by a longshot. In Oblivion, ruins, dungeons and caves are just found out in the wilds (because Cyrodiil has a legit wilderness!) as Skyrim's dungeons have a little dirt road to nearly every entrance. The one thing about Oblivion's dungeons is that they could be more hand-made and less copy-paste; also, the caves shouldn't have a wooden door in front of them (due to the fact of them being uncharted).
I realize Oblivion has already been done; that Bethesda has never done anything like this; and that people have already adventured through the realm of Cyrodiil... but the world of Oblivion is the ideal open world I have always wanted, but it lacked in graphics and gameplay. I can only hope that one day, Oblivion will consider this (or some other game developer will make an open world RPG with the "perfect" terrain). It would be a dream come true if they made this a project and made it happen.
What does everyone else think? Do you think this is worth it? Would you like for Oblivion to be remastered and play it in a more enjoyable way? Or should they just leave it as-is and not even bother?
