Since we don't exactly know what will be implemented in the finished game, we could as well write a list of all things we'd like to see as a feature. Please define the things you want and than write a reason, what you mean, or why that would be a good addition, like such:
I'd like to see these in Skyrim:
-More denominators (gold, silver, copper coins so prices could be more realistic) - Not Done
-Stealthy spells (for our rogue/thief/assassin/ninja character to be able to cast quiet magic) - Done
-Disguises (so you can blend in with the enemy) - Partially Done (A certain quest by Delphine)
-Pets (if you can buy a house, add some life to it) - Done (Can buy dog!)
-Titles of nobility (as you do good deeds, you should be rewarded) - Done (Become Thane)
-Secret places (hidden dungeons and such, without a map marker) - Done
-Chargable spells (so you can add more power to a finishing touch) - Done
-Lots of cookable items (diversity is everything) - Done
-Government offices (so you can roleplay better) - Done
-Mail (for sending invitations/requests to NPCs owning a shop, or offering a service) - Done (courier)
-Trap setting (achieve your dark deeds by setting a trap, that nobody knows you made) - Done
All that have been implemented are marked at the end of the line.
Can you see this? Almost everything I wished for is in the game!
So I send you a big thanks Bethesda for paying attention to your fans and making Skyrim so great!
