Was I wrong about the LotR Card Game?

Last September, I posted that the Khazad-dum deluxe expansion for Fantasy Flight's Lord of the Rings Card Game was more of a commitment than I could bear for this product line, and I dropped my desire to buy into the game. Too rich for my blood, I thought, and I feared it wouldn't give me the solo satisfaction I required.

However, today on that very same post, the awesome Ninjadorg - for whom I have great admiration - left a comment that has me reconsidering my decision.

From Ninjadorg:

It's a shame guys, you're missing out on a beautifully developing solo game, with more theme and gameplay options with each new release. And Khazad Dum is easily the best expansion pack so far.

Yikes! Was my original assumption wrong?

I really want to hear what others have to say about this, so please - if you've played this game - comment below!

Thanks!
