Skyrim has a lot of npcs, places, quests, choices, weapons, clothes, armors, powers, etc that got removed from the game and some of these things can be accessible using the console command in the PC version, but why bethesda dont add or make these things accessible offically in the skyrim remaster, even new enemies could be added.
Lets be honest who doesnt want to kill maven black briar and delphine and esbern, who doesnt want to have the ancient falmer armor complete with the crown without having to cheat, who doesnt want to see that wintersand manor place that nazeem has a key for and the list goes on an on. A lot of people would say about mods, but something official would be more awesome, like npcs, guards, etc reacting to those events and commenting about it with you and these deaths or choices or whatever effecting skyrim in some way, same goes for new weapons and armors(like guards talking about the mace of molag bal or dragon armor when you have them equipped).
