This is great revision of the original expansion set despite this means you have to spend the money again.  And this revision makes the old one completely obsolete-so if you're like most of us Arkham players, that was money down the drain.  But if you are like most of us Arkham players, you'll still spend the cash to buy this new revision and still think it's a great improvement.  If you're a new player-you lucked out!  Buy this product as it's pretty well play-tested as none in my group had a problem with this and thought it fixed a lot of issues from the original.
