Summerset Isles, I am sold. If I worked for Bethesda I would implement a coupld new things to this new setting as well. so here are a list of ideas Bethesda, don't forget I wold be a cheap consultant.. lol
1. Boat/ship captain. I feel like it would be totally awesome if there was a quest line in which you can buy/find a ship that you own and then can handpick a crew of NPCs that will fulfill the roles necessary for the ship. There could be some EPIC ship battles not to mention sea monsters, pirates, dragons, just about ever kick ass thing you could imagine.
2. A team. I have already done this in Skyrim on my own just pulling NPCs where I can to make a company of adventurers. I feel that if they actually added into the game the need/use of a group of NPCs into the main quest. I mean it should be optional to use them or not, maybe a communication spell that allows you to teleport backup where necessary. I feel it needs to be scripted well so you don't feel like killing them right away, maybe some awesome combo benefits.
3. At least 1 giant battle scene. Now I have not gone too far in the Skyrim main quest and they may have touched on this already. I would really like to see a huge LOTR sized battle at the end of the game. Large enough to where you could spend Days getting through hoarding masses of battling folk and monsters. Maybe a castle siege in which you have to defend or attack.
4. Alteration needs a overhaul. I know there is no flying and that will remain the case. But wouldn't it be awesome if you could cast a jump spell that could make you jump entire buildings. Or a giant spell where you triple in size for like 60 seconds. Or a shapeshifter spell, become a monster or another race. Maybe a quest where you sneak into a location not by using invisibility but by becoming a monster briefly to get through.
5. Finally (Sorry bethesda you dropped the ball on this one) Climbing. Skyrim should have had climbing featured in it. Soooo many games if you are on a ledge you can climb, or if you jump next to one you climb up. For a mountain scape RPG that boast free roaming, I think having to run up a 80 degree angle just seems a little silly.
