I would avoid it. As "nice" as the idea might sound on paper there are many ways that it could go very, very wrong. Look at Dragon Age 2 there were many posts saying the only thing really wrong with the game is that it wasn't an open world game so that is what Dragon Age: Inquisition is and people are upset because it has all the short comings of an open world game.
I'm sorry, but that's not true. Most people's problem with Dragon Age 2 was that it reused the same environments over and over and over again.
People wanted questing to take place in more varied environments -- like the environments in Dragon Age: Origins.
Very few people, by comparison, demanded an open world. The open world was largely BioWare's idea because BioWare chose to compete with Skyrim.
And I'm sure that most people who did support Dragon Age becoming open-world wouldn't have approved of open worlds with such shallow content.
So please don't act as though BioWare gave us exactly what we wanted and we're still not happy. They didn't.
(Gosh, it looks like I can't avoid this debate. lol)
I am pretty sure [a Dragon Age Telltale game] would work exactly like a slightly reskinned Game of Thrones game and frankly I prefer the books and television series of Game of Thrones more then what Telltale has offered with the first two releases. Which leads to my other major issue with Telltale games, their release schedule from my experiences never release on time and dislike the episodic release for it feel always like DLC instead of a cohesive story.
Fair enough. These are good counterarguments. I also wish that we didn't have to wait so long between episodes.
I think I'd prefer the entire season to be released in one go.
