Alright, so let's talk about things you should know. First off, you're playing D&D Next (also called 5th Edition), and you've got the basic rules .pdf, which is perfect. That's exactly what you need. And if you already know how to fill out most of a character sheet you're ahead of the curve. So, let's start at the beginning with the core mechanic: Basically, in D&D, you are going to have full control over a single character. The Dungeon Master (or DM) is going to describe situations to you and you have to describe how this character you control reacts. However, in many cases when your character attempts something, you roll dice to determine whether your character succeeds or fails. Basically, if the success of an action is in question, you roll a d20 (a twenty sided die), add a modifier to it (usually representing your character's skill at that action) and compare that result to a specific number (set by the DM) to see if your character succeeds or fails. As long as you're aware that you'll roll a die to determine how well your character will succeed or fail, you're ready to play some D&D. So, that's the core mechanic. With that out of the way, I need to have a serious talk about HOW to play this game. Then in another post I'm going to give you another way to look at it. Basically, when you play this game, you are taking the role of a leading character in a TV Show or a Movie. A swashbuckling hero, a street urchin with a heart of gold, an unparalleled soldier, a mousy, insecure wizard, etc. No matter what you choose to play, it's important to think of this character at a person. They have things they want, and they react to situations as any ordinary person would. They avoid dangers, they want rewards, they have likes and dislikes, and they have things they want out of life. As you play this game called D&D, you'll be constantly asked 'what are you doing?' or 'what do you do next?' And if you don't understand what your character would want, then you're going to have a tough time answering these questions. So when you get into a situation in the game, imagine that your character is a TV character, or a movie character, and then think about what you would expect that character to do in that situation. Alright, that's enough for now. Let me know what questions you have and then we'll get to the advanced stuff. ;)
