Lord of the Rings Online might be getting Mirkwood (see below), but World of Warcraft is getting Peggle. I can think of no way to better highlight the difference between these two fantasy MMOs, and I say that without a hint of judgment. That bit of information -- one game gets Mirkwood, another gets Peggle -- pretty much tells you all you need to know about which is the right game for you.

You can compete, you can goof around, and you can even advance up a new Peggle talent tree. There's even an option to use Peggle shots to determine who gets loot.

By the way, when Bejeweled found its way into World of Warcraft, the concept and implementation was from someone who didn't work for Blizzard or PopCap. The same guy came up with the Peggle idea, but he no longer doesn't work for Blizzard or PopCap. He begins his new job with PopCap in a few months, just as soon as he finishes school.
