(I played Morrowind more than any other Elder Scrolls therefore I'll be using that as examples)
Following the the Elder Scrolls Skyrim, I hope I see you all doing your best to make this your next best gem.
I urge you to make a truly great Elder Scrolls game, dare yourselves to push your own limit and beat your past accomplishments, and make Skyrim the new gem of the Elder Scrolls series. To many times in the past 5 years I've seen 1 crap game after another come out, where the developers put very little effort into everything that makes a game great, but I still have hope in Bethesda.
When creating Skyrim, The world, the story, the mechanics, dont forget to also make the world itself feel real and alive. Give the game atmosphere, let the world breath as though it is real. Nothing should feel like a set.
Make every mine, cave, ruin, etc. different, throw in hidden areas like in Morrowind. Going in 1 cave was never the same as another. It felt as though every building, town, area was lived in for centuries. Never knowing what to expect around the corner. Or who occupies the cave. Sometimes going into a cave and finding slavers, and being able to talk and communicate with them, not just being attacked on site. Sometimes finding an Abondoned Druid Alter deep in another cave with offerings still fresh as though someone had just been there. There were so many countless things to explore and do. Perhaps I'm exploring along a rocky coast, and I come up across a beached ship, I decide naturally to explore it, find cargo, pick whatever I need or want, and lock pick the captains door. Inside I find a skeleton with a book across its lap, picking up the book, I begin reading, its about the voyage, what happend, why it beached and the tragedy that befell the crew. The immersion, realism, and atmosphere in Morrowind was to this degree, and I urge you not to forget this in Skyrim.
And we must not forget about quests. Atmosphere may be the bread, but quests are the butter that makes it worthwhile. Again reffering to your gem that is Morrowind. A game I still play to this day; Quests in Morrowind, unlike Oblivion, could be complete in more ways than one. Sometimes up to 5 different ways or more if you really broadened your mind to it. They also were not revolved around the player, but around the world itself. Oblivion felt like all the quests were made specifically for me. This isnt realistic and broke the immersion of the RPG factor that truly made past Elder Scrolls great.
Again for quests, in Morrowind everything was there... if someone talked about needing or wanting a deed to a piece of land, it was already there, SOMEWHERE in the world. Someplace even if I didnt have the quest triggered, was there. This again made the immersion and realism all that much more, and added to the RPG factor. If I needed to get a land deed from an old lady, I knew it was SOMEWHERE in her house.. perhaps I could look for it? perhaps its in a locked chest? or I could do the quest for her and help her out, and that quest had more than 1 way to complete it or go about it. Every quest had more than 1 way to complete it, allowing me to do it how I want, and how my character would do it.
Guilds and Houses in Morrowind were also intrigueing and in depth. The story of how some of them intertwined. Even the hidden assassins guild that you only know about if you happen to stumble across it in a very awkward and un expected area. A guild that rewards me and makes me a member for finding it. Again just heightening the immersion of the game that much more.
I urge you, please do not forget the meaning of an RPG. An open ended world where anything is possible if I can think it up. Where the world feels lived in and real, and the atmosphere and personality of the world itself is true to what it should be.
This request is not even touching on the fact I want to be able to wear every piece of armor. Chest, Pauldrons, Gauntlets, legs, feet, helmet all seperately. To have more than 1 look copy and pasted with a different mesh, and to bring back the wide variety of weapons that were in Morrowind. Staves, magic staves, crossbows, long bows, short bows, daggers, short swords, long swords, 2 handed swords, 2 handed axes, 1 handed axes, Spears, Halberds, maces, Hammers, and the like. All looking different, all looking to match their type *silverite, Iron, etc.* And there being a very wide variety of it all.
Strive to make Skyrim the next best thing to hit the gaming world. Pretty graphics with lots of action wont cut it, to truly make it gem and make the fans and create new fans, you must have everything else first. Atmosphere, open ended world, open ended quests, and everything else mentioned above. That is what makes gamers become fans, and what makes the fans come back again and again for years to come.
