About First-Class Letters, from BoardGameGeek:
That mail truck is driving way too fast. Packages are rolling down the street and letters are flying everywhere. We'd better get this in order or else it spells disaster.
First Class Letters is a roll-and-write word game played over 7 rounds. Each round players write a word on their sheet using letters rolled on dice, as much as they can. The words on their sheet must be kept in alphabetical order, or be cancelled out!
The "dead letter" die provides a letter players must not use each round, and "priority mail" provides a letter that must be used.
First-Class Letters can be played competitively, cooperatively, or solo.
