I'm not exactly sure this fits with TES but a concept I've been really interested in as of late is an adventure game where life has value. In Skyrim you kill people left and right without remorse, who cares. In TES VI, it would be so cool if death wasn't the first thing you jumped to. By all means be a bad guy sure, but the fine system is a joke as is. Murdering a full town should have lasting consequences beyond just basic gameplay ones.I feel like this is something that Bethesda has talked about trying to do, but their actual attempts have always been lackluster.
The more I think about it, I feel like Skyrim is a game that does a lot of stuff, but it doesn't do very much of it well. Although doing a lot of stuff is kind of the whole point of the game.
Lastly, minimal glitchesMade by not Bethesda then!
