Some people have already said they don't care for 5th E Dungeons and Dragons, but I'm ready to embrace change. The starter box comes with some dice (added to the pile), 5 pre made 1st level characters, core rules, and a pre made campaign.
First off, the 5 pre made PCs. Normally I shy away from pre mades but I really like these. They all have interesting backgrounds and everything to do with stats and gear has been filled out for you. They left character description and names blank, so the player can customize. On the back of each is a guide for developing stat wise as you level up. Again, I really like these and can see a lot of use for them. Either as a guide for making your own, or a quick way to start a newbie while still giving them the chance to develop their own way.
The core rules are all there. Combat, Ability Checks, Equipment, and anything else you need to know to get playing. It is easy to read and provides detailed examples of why you make certain rolls and how they affect you. It is well formatted and directs you to relevant pages clearly.
The pre made campaign seems cool, I haven't fully looked it over to be honest, but I will soon. As a bonus, the back of the pre made campaign book has a lot of monsters re statted for 5th edition, which is nice because the monster manual wont be out for a while. It also comes with a guide for how to run games for players level 1-5.
All in all I feel it's a great way to jump into 5th Edition with a clear sense of direction and purpose. I am really psyched to keep playing, and it justifies its $20 USD price tag.
