Not necessarily grave robbing. Even looting Draugr or the burial urns etc just seems wrong to me so I'd rather stay away from digging up graves to loot them, that's seriously screwed up stuff and I don't think it's right for Bethesda to encourage that sort of thinking.
It could even be a quest: "My son buried my valuable amulet somewhere near the Skyforge, it was a family heirloom, can you find it for me?"
damn kids these days... oh, wait, i'm technically a kid (teenager, whatever)
i agree that grave robbing seems wrong. Draugr don't seem that off-limits to me, but graves should be sacred
i'd like a hardcoe Mode. perhaps a yellow bar for hunger, optional features like the Frostfall mod, fatigue (as in needing sleep, not TESIII/TESIV stamina bar name) etc
more stuff for marriage system. adoption would be nice, perhaps hug and kiss animations. a proper proposal, not just admitting that you like an NPC, and they immediately assume you want to get married. something that makes interactions between you and your wife/husband feel like love, not slavery.
a UI for PC that doesn't revolve around a controller. something like SkyUI. but if it was added, console players would complain that the PC gamers get a special UI (that is meant for a mouse and keyboard)
more "good" choices. i don't wanna kill Grelod for the Destroy the DB quest, and i wanna destroy the thieves guild
that damn Dawnguard DLC. hurry the [censored] up, bethesda.
pets. perhaps a cat that wanders around your house, and your spouse or housecarl play with it
if adoption was added, the kid should interact with the local children, and perhaps become an apprentice blacksmith, stable hand, hold a bake sale in the market? etc. give them a dagger or child-size bow to defend themselves, and train them how to use it (mom, i wasn't trying to shoot your best plates, i swear!)
also, pranks, and the ability to go on a pranking spree with them. water bombing guards, linen-wrapping market stalls, stink potions in the pub etc. then getting told off by your spouse (or not, depending on how fun they are)
proper jobs
