Flower is the best selling game for the Playstion 4 on the Playstation store in November. While that may surprise you, Flower is an excellent and beautiful game, not everybody's cup of tea, but anyone who purchased a Playstation 4, they received $10 to use on the Playstation Store. And you will never guess what game is under $10. Flower costs $6.99, so you can probably assume that people spent their free money on Flower. Sony also released numbers for Playstation 3, Vita and more.
