The first game I ever picked up was Magic: The Gathering. Back at the time, the only card games I'd known of were Gin Rummy and Poker. So the idea of a game where you can build your own deck just sounded weird. But like most, I soon learned exactly what that all meant and it opened up a whole world of hobby gaming for me. That world, of course, included Dungeons & Dragons. But my first game and my most-played RPG remained separate. And that way they remained for decades. That is, until now, with Wizards of the Coast posting a Magic: The Gathering/Dungeons & Dragons crossover pdf.
The pdf is free to download from the Magic: the Gathering website. It takes the world of Zendikar and gives you all the stats needed to play games of Dungeons & Dragons in that world. I know this is something that a lot of gamers have attempted to do on their own for quite some time, but now there's a semi-official version of it (I say "semi-official" because the stats and rules haven't been fully playtested yet. So you could consider the set sort of an "open beta" version).
