An expansion that does a better job of adding interesting bits to the story.
First off, this game does little to improve on the graphics of the previous game, but it does add a couple new environs that look really cool. Some of the new heroes also looks pretty neat. Overall there isn't much good or bad to say in the graphical department.
The music is more of the same, which is most definitely a good thing. A lot of the new dialogue is just as well done as the previous game as well.
All that stuff isn't important though, because what really pushes this game is it's content.
In the single player campaign, there is a lot added as far as story goes. The story continues and actually adds quite a bit of interesting information into the lore (very important information that is in-fact important to the series as a whole). The campaign has it's own varied missions as well, which are appropriately challenging. Then there are the additions to the multi-player. There are a ton of cool new maps, but since the game doesn't add any new units or any interesting upgrades to the mix, the same strategies still hold true. This means there are no new dynamics and so the gameplay in multiplayer essentially remains the same.
As far as single-player goes, you will find a lot to enjoy here, but with the ability to play custom-made maps, the addition of these new maps (although well done) will not necessarily be an effective draw. Still, it is an overall solid expansion that is a fairly worthy addition to your Warcraft collection.
