Souvenirs

Souvenirs is a card game in which players collect valuable collections of travel souvenirs.
There is a row of open souvenir cards on the table (one card more than there are players in the game). Each player has a set of hand cards. In each turn, players select a hand card that marks the souvenir they would like to collect. Cards are revealed simultaneously. If a player was the only one who chose a certain souvenir, they can collect it; the unclaimed souvenirs are cleared and can reappear later. When a player has collected a certain set of souvenirs, they can claim a mission card.
At the end of the game (when there aren't enough souvenirs left for a new round, or when all mission cards are claimed.
Scoring is for each souvenir, for claimed mission cards and for certain preferences of each player (each player has a favorite continent, for example). Highes score wins.
