I was thinking about this looking at the site of the elder scrolls suddenly and got this idea. The only TES adventure game has been Redguard. However I think there's a high chance for another one in the upcoming future. Personally I don't want it because I'd assume it wouldn't be made by BGS...

I want Eye of Argonia :sadvaultboy:

Its probably not going to happen, and if it does, it probably won't be made by Bethesda. Redguard flopped and nearly took Bethesda down with it, and last I've heard they weren't too eager to repeat it. Of course they are much better off now, but they are also focused on a very specific type of game.

I'd like to see a spin-off series, but I doubt it''ll happen within the company - maybe by Obsidian?

(and before anyone goes LURL BUGZ, Dungeon Siege 3)
