Also let me clarify something and go back to the original proposed question: Obsidian doing spinoff of TES.
Allow me to briefly tell a story.
Once upon a time, there were two series. Battlefield, and Call of Duty. Both were very different, and each had their advantages and disadvantages. Battlefield 2 offered a very paced, slow playstyle. It encouraged teamwork, had vehicles and the maps were huge. It was similiar to being in a large scale conflict.
Then there was COD: Modern Warfare 2. It entailed faster gameplay, focusing more in indevidual skill and perception. It had no vehicles and focused on infantry gameplay, and had smaller, more concise detailed maps.
Though people have fueded for years, simply put, the games are different and cannot be compared. They simply cater to different play styles. However, now BF3 is out, and it's no longer a true Battlefield title. Why? Because they saw COD, and copied too much of it. BF3 is essential now COD with vehicles and bigger maps. Same fast paced gameplay, same focus on indevidual talent. They are no longer two seperate games each with their own style, but rather two competing games that are very silimiar.
I don't want that to happen to my TES. Obsidian has a certain style, which plenty of people enjoy, but it's very different from Bethesda's. I want it to remain that way. This way the people who like their style, can go buy their games and enjoy those, while at the same time, those who enjoy Bethesda's style, can buy their games. They are two seperate styles, that cater to two seperate groups.
If Obsidian starts doing TES games, then they change that style of the TES game. It no longer caters to Bethesda's fans, but rather their own. It's muddying the waters by combining two seperate styles into one, inevitably leaving someone out in the rain, instead of keeping them two distinct seperate ones.
Let Obsidian make their games their way, and Bethesda make their's.
Anywho, enough word walls for me.

I've said what I came here to say.
