Gah! I'd never seen it next to a "normal" sized edition, so had no clue it was actually bigger.
The clamshell type box doesn't bother me so much, but the size does... there's no need for it to be that big, surely?
I don't own the GoW edition, but do have the Uncharted 4 one which is also a clamshell, although it's much smaller (same size as GoW I'm guessing). The one for No Man's Sky was really nice also!
