1. more major factions can be created from the turmoil that Tamriel is in at the end of Skyrim, even the return of the Akavir,dwemner, snow elves even a new dragon race.
2. More weapons and armors can be made form new smithing techniques, to even new types of materials (ores).
3. Allow for more spells even new types of magic classes.
4. the creation of New guilds giving far more joinable situations for players, as well as the return of the old classics like the thieves guild and the Mages guild.
5. With more spells this will allow for far more enchantments
6. Return of the ability of the deadric princes to return to tamrial (Heralded by Malog Bal) . This caused by the use of the eldercroll to travel back in time by the DragonBorn to give a simplified reason why they can return. The elderscroll by using its Boundless power to travel back in time could be a reason for many of the events in the eldercrolls MMO (almost endless possibilities).
7. Morrowind was awesome (favorite game of all time) imagine what a rebuilt Morrowind (mostly Vvardenfell) would look like.
8 Just the fact thier could be endless ways of future to be and you have the choice as players to changes the eldercrolls for the future. Endless new types of enemies, or even completely unknown new races.
9. Please discuss and add to if you like.
