I was thinking maybe take us back 1E 800 on the contenint of Yokuda when the Radguards were at war with the left hand elves, or maybe sometime in 1E take us to Atmora, maybe take us to the 5E Tamriel, and add some more playable races, but just something to keep the series going and fun

The first four games were within the lifetime of one Emperor. Why would the next game have to be in some random time period? There's plenty of stuff set up in Skyrim that could be dealt with in other games.

Feel free to leave your thoughts on this and post your own ideas and maybe we can get someone at Bethesda to this!

This thread is where people post suggestions for future TES games:
