EB Games Canada has a good deal on World of Warcraft: Wrath of the Lich King Expansion Pack, get it for only $9.99.
A bit of an older expansion pack: but one that was very well received. It has a Metascore on Metacritic of 91… which basically means it ROCKS.
Here is one reviewer’s opinion that I liked:
Wrath of the Lich King takes the best-of-breed MMO and improves everything about it. It’s a work of supreme confidence and quality that is twice as fun and ten times as beautiful as classic WOW, not to mention anything else in the genre. But above all else – in the breathtaking sweep of Northrend, in the assured, epic storytelling, in the constellation of brilliant quests – it is a grand adventure. Perhaps the grandest adventure in all gaming.
