I would like to see them create an even smaller world with more detail. By that, I don't mean graphically, I mean detail in interaction. Like opening up the closet and cupboards in Shenmue to see what was inside, or how you had to just ask a whole bunch of people and investigate to feel what was going on.|
Both of these are in previous Elder Scrolls games, but I feel like while there may be a good deal granular detail they try to do so much, then none of the details feel designed. So for instance, in Skyrim or Oblivion is you explore everywhere, you mostly find either Time for Exposition text deposits or items that aren't all that memorable. I'm talking more about putting a small trinket in a cupboard no one would usually investigate and make it so it links to some random NPC in a few towns over, where you would only get some meaning if you had followed a couple of different quests or conversations. Bethesda and Obsidian did this to a certain extent with Fallout, because everyone expects that kind of detail from Fallout. Yes, this takes a long time and is hard to do; that's why I recommend they drop epic walks into nothingness for being overwhelmed by the detail in a smaller space. They've certainly got the manpower.
As for actual real investigation, its just a pipe dream, because the minute they do it, there would be reviews about how the game isn't designed well because people don't know what to do and mega blockbusters just won't take that type of risk.
If I had those two things, and design like them, I would be on cloud nine. I do not expect good writing or a good battle system or good dungeon design from this series, as it is more of an RPG simulator and all that stuff can come from players who mod it later, so I'm not that picky.
Though I am kind of upset that the next game probably won't be in a snowy environment since snowy Santa places are my favorite in games.
