All right - as promised last Tuesday - here's what you need to know about the Adventure Card Game Organized Play.
First of all, here's a link to the Organized Play Guide for the ACG:
http://paizo.com/products/btpy98no. Although much shorter than the RPG Guide to Organized Play, it's still a heavy read. I would recommend browsing it, but this summary should give you the basics of what you need to know.
First of all, much like the RPG, the ACGOP is made of scenarios, and the scenarios can be played out of order or even skipped if you miss a week. Each scenario is also part of an adventure, a group of 4-6 scenarios. Your character gains a reward for each scenario completed, and also gets a bonus award if you play through the entirety of an adventure, so usually it's a good idea to try to play all of one adventure on one character. Six adventures make up an adventure path, and each season represents one adventure path. The current season is Season of the Righteous, which is the Wrath of the Righteous Adventure Path.
The equivalent to levels for the ACGOP is Tiers. Every character starts out as Tier 1, and can level up to Tier 6. Unlike in the RPG, ACG characters don't level up all at once. After playing your first game at a tier, you get a skill feat. Your second game gets you a power feat and your fourth game at a tier gets a card feat. (Skill feat adds numbers to your dice rolls, power feats improve your character's special abilities, and card feats give you more cards for your deck.) After your fourth game at a tier, you can advance to the next tier. Every card has a number or letter in the top-right corner of the card. You may only have cards in your deck whose number is less than or equal to its tier.
What you'll need to bring: The two major things you'll need is Dice and an Class Deck. This is what the Class Decks look like:
http://paizo.com/pathfinder/adventureCardGame/classDecks , and I know that Redcaps has some (and there's a full set at Baltimore Redcaps which I'm hoping they'll bring over.) I'll have some to lend, but I don't own all of them myself, so my hope is that at least some people will have them. You can build your starting deck from the Basic cards in that box, using any character that deck provides. If you own a Base set that has an iconic with the same class, you may use that one instead. (For example, I intend to play the Cleric class deck with the Kyra that is provided in the Wrath of the Righteous box.) The only other cards you may add to this are if you have the appropriate promo from the Iconic Heroes Line.
There's a bit more you need to know about the end of the game, but we can talk about that on Tuesday when we get to it. (aka You have to remove all the cards that you earned over the course of the game and you get to instead choose an appropriate upgrade from your class deck box.)
If you have any other questions, please feel free to ask. (Although I'm in Providence right now, so I may not be able to respond quickly)
