Nostalrius Begins - Quality wow vanilla realm (1.12)

I was wondering if it was possible to install/run nostalrius begins on a portable flash drive, and if so how much data would I need for it in total.

Yes it's possible, all though the game may run slow if you are using an older USB flash drive.


I think the game takes up around ~6 gb.

On an harddrive install:

(includes ~30 addons)

I would say a portable version would be around 5-5.5GB, so Al4n may have it right.
