P4: Gritty Reboot

That's why it's called Legacy. Each time you play leaves a legacy that affects subsequent times.

From reading about it you put stickers over the board, write down your own countries names, tear up the cards it comes with (which you've mentioned yourself) and there's several single use packets to open up randomly in each box. It doesn't sound like a game where you put the pieces back in the box n fold the board up.

But that seriously is the whole point, to play it more than once. It's just that you should be playing it more than once with the same people, not on somebody else's board. Stickers on the board from previous games give bonuses/penalties in subsequent games, cards get removed from the deck as they're destroyed, your copy of the game evolves and becomes unique over multiple play sessions.
