The official ESO website stated that the beta will be around 20 GB. I was expecting a lot more for almost the whole of Tamriel. Does this mean we'll get a lot of re-used materials, smaller worldspace and less quality overall? I'm disappointed in knowing this... Should be atleast 30 GB, knowing Skyrim is around 10 GB.

MMO's seem to be getting bigger and bigger. 20 GB's at beta sounds -huge- to me. I think TOR was only around 15? Oh well, where did you see this on the website?

Skyrim is 3.8GB for the 360 and about 6GB for PC.

What takes up the storage space isn't the worldspace, but the textures. And the game is not that graphically intense.

Some things to consider

* That is the beta client.
* May only contain testing material (limited areas, etc)
* 20GB is huge amount of data if optimized well.
* Probably redundant graphics files like hi-res textures are excluded.

And more...
