Some of my personal favorites
- The variety of the dark brotherhood quests in Oblivion and guild quests in general
- Quick travel after a place has been discovered
- Levitation in Morrowind
- The spell casting system in Oblivion
- The ability to train your character's combat skills in Morrowind (Some people hated this)
- The music in Oblivion
Some of the worst parts
- The repetitive nature of many quests in Skyrim
- Dragons in Skyrim
- Being "prophesied" as a hero, I'd rather earn my way than be born the "Only one who can save Cyrodiil/Skyrim"
- The main quest line in Skyrim had little interaction or decision making
- Moral decisions being left out of many quest lines and quests not being open ended
But one thing that has been proposed for elder scrolls 6 is the construction of buildings, as in chose the colour, shape, design, theme, location and size of your house. It has even been proposed that you get the chance to build your own guild. Any thoughts?
These are only my thoughts but please don't post something like "Coloured Armour" or "Dragon/Tiger Mounts" as these things obviously don't belong in an Elder Scrolls game
