"Truly Epic Expansion"
Since the Cataclysm Event in-game, I was content for a while to simply revisit the Classic world and appreciate the redesign that had accompanied its shattering. The zones flow much more seamlessly, and tells a much more powerful story.
As usual with a new WoW expansion though, there are certain additions that can only be accessed by upgrading, even excluding the new zones and boosted level cap, such as the ability to use Flying Mounts in the old world, and the new secondary profession of Archaeology.
These alone are a powerful draw card for the expansion, and go hand-in-hand; as the Archaeological plots move around the continent as you exhaust each one in turn, the ability to hop on your magic carpet (for example) and zoom to the next is an immense time-saver.
The new races are another good reason to upgrade, each with their own brilliantly written and cut-scene intensive story throughout the beginning levels, until you join the normal flow of Azeroth.
Perhaps the greatest reason why you should make the jump from WotLK though is the new zones with their well thought quest chains, presented in a relatively linear fashion within each zone, making sure that it is hard to miss any of the crucial content and lore. Each zone has its own near-unique texture set that brings out the environment in stunning detail - be warned that for best performance you really need to at least double the stated requirements - I recently upgraded my machine and still experience sub-30 FPS in some particularly intense areas; if you want to have the graphics settings at max, you'll probably need an SLI or Crossfire system.
With all of this going for the expansion itself, why go for this CE you may ask- Well it depends on how big a fan you are, really. The included in-game pet is clearly going to be negligible for some but an incentive for others (like myself) and similarly the trading card set is of little relevance to those who are just into the game, and not the offshoots, but a definite bonus for others.
The mouse-pad also might be seen by some as a trifling addition, but personally I replaced my previous aging pad and immediately noticed the difference - it is not just some cheap and flimsy pad with a fancy printed image, thrown in as an almost-afterthought, but a high quality and hard-wearing product that also adds a little extra to the dekstop ambience.
The included hard-cover book of concept artwork is a magnificent addition, really making you think again about the amount of effort that has gone in to the new modelling, and you may find yourself taking a much closer look at the designs as implemented in-game than you otherwise would.
Similarly the DVD packed with interviews gives you a glimpse behind the scenes and lets you appreciate just what a mammoth task putting together a game like this must be.
Finally, the included soundtrack CD gives you the chance to take a bit of the Cataclysm experience out of the game as well - I'd recommend first playing through the game and hearing the score as it appears in each zone, so then upon listening to the CD by itself you can close your eyes and imagine yourself flitting between the Vash'jir reefs on your Seahorse mount, meditating beneath Nordrassil on Mount Hyjal, or surveying the secrets laid bare by the discovery of the deserts of Uldum.
In essence, if you just want to play the game and see and do the new features that are offered, the normal expansion will suffice, and still deliver a sterling experience. But if you want to really feel and become involved in that experience, and be able to appreciate the hard work Blizzard has done in creating the greatest WoW addition yet, the Collector's Edition is the only way to go.
