Matt is an Apple technician by trade, but enjoys playing table top games of all types and difficulties in his off time. He made Thrift Shop because he used to be forced to play Yahtzee! at family functions and hated the game. To relieve himself from Yahtzee!, he would find different games that he could play by himself, without walking away from the social construct of the table. This worked well because it served several functions:
1) Everyone else at the table was happy because they never lost at Yahtzee!, they always knew they would beat Matt
2) It allowed Matt to escape from Yahtzee!
3) his first game was created this way!
