I'm a big fan of DJMAX Games and I was really surprised when I saw this one in steam's christmas sale. it has a lot of content from all previous games so if you were a fan of those you are in for a nostalgia trip. It is exactly as you would expect, and it has online multiplayer that is a nice addition.

The only thing that I don't like about this is that is in my opinion way overpriced, and there are some games (like Black Square) that are locked behind DLC, would only get on a sale. If you are a real fan you won't regret it.
