The weather of December 2010 in the UK did result in quite a late shipping for my copy of CE, having had it pre-ordered since September and it only arriving on the 20th through Royal Mail. As a long-term player of the game since classic/vanilla I was actually rather amazed how soon I found myself enjoying the challenges and features of Cataclysm. There was a certain early quest in Hyjal featuring a certain fire elemental we all remember from way-back-when, which I won't spoil, but the design of that specific event had me grinning ecstatically. It's been a long time since levelling content has done that for me in WoW.
The box itself: well the mousepad is glorious, the CD is some excellent music, haven't watched the DVD yet, and then the artwork book is excellent.
Collector's Edition remarkably worth the £50 I ended up spending.
