every land mass of tamriel has been included in skyrim. morrowind, cyrodil, high rock, hammerfell, blackmarsh etc... it's all there. cyrodil even has the white gold tower and morrowind has black mountain in vvardenfel. heres a video of a guy flying around tamriel in no clip mode in skyrim:

I don't know if this has been posted yet so i apologise if it has. but, i mean, beth added all of tamriel into this game. why? wouldn't this put so much stress on the game? maybe this is why the game is experiencing so many issues. still pretty cool though

so... am i the only one that finds this interesting?

I think this has been covered in another post.
However, I do find it interesting.
