Scenarios are a single session, with Adventures being a series of scenarios and Adventure Path's being a series of Adventures. This offers a massive amount of flexibility and replay value as you not only have a seemingly endless supply of journeys in the base box, but replaying them, and replaying them with different characters will lead to new experiences every time.

Each character has a stat card, showing you starting hand size, skills, and powers, as well as having room to acquire new powers. Don't worry though, if you aren't the kind to mark up your cards, Paizo has a tremendous set of downloadable files you can use instead, and write on, doodle on, or whatever-on as you see fit.

From there, it's setting up your location decks, as listed on the scenario you are playing. It's as easy as pulling random cards from the box of each type listed, building a deck of about 9 cards, adding a villain or henchman and knowing some basic information, and getting ready to explore!

Exploring is the primary action, as it'll uncover the top card of the location your character is at, and allow you to engage in a fight to eliminate monsters and potentially find the big bad guy in the scenario, or find wondrous items, weapons and armor to acquire for this and future fights.

This is where the "Evolution" part kicks in. You both will acquire cards to use in this setting, but also then, in between games, be able to use the found cards to "remake" your deck, as well as help your fellow heroes by trading cards with them. So while a bard may explore and find a sorcerer’s staff, they may very well want to acquire it and ensure their party members grab some phat loot!
