Basically the game has packets with instructions like "open on game 3" or "open the first time an army is defeated". These packets then have things like extra cards, new rules, new marks for the board. Speaking of which there are marks you put in the board for different victory conditions, like you can "own" a continent whicheans in future games if you own that continent you and only you get a bonus. Same with naming a country or buffing a country so it has a permanent +1 army. If you have enjoyed Risk previously and have a group of friends that you can continually play with I'd highly recommend it. It can still work with mixing in new people but half the fun is the shared history and friendly rivalries between game sessions. Also there is a certain feeling when you tear up game pieces (or burn them as the winner in our case).
