There is a lot to like. As I've already commented, it's great to see credit given to the creators of the original game (E. Gary Gygax and Dave Arneson, with Brian Blume, Rob Kuntz, James Ward, and Don Kaye). There are also some kudos thrown at more recent contributors, some of whom most D&D bloggers will recognise, for their work as consultants. For example, Zak S and RPGPundit. Apparently, according to their respective blogs, this came as a shock to many. Now to be fair, I follow both of their blogs and in my opinion, each can come across as 'a bit of a dick' at times. However, there is no denying they care about the game and roleplaying in general. So, bravo Wizards of the Coast!
Rather than wax lyrical about what I like (and don't like) about the new rules, I encourage you to download the game and have a read yourself. Meanwhile, I'm going to start designing a cover for my copy. Remember, as always, the game is what you make it.
