I started to play just about 3 months or so ago and I only really have time to play at the weekends, so I am taking it slowly and try not to overwhelm myself with too many animals and content at once, but I did bought the Arid pack right after it released because I liked the roster and additionaly with it bouth the South America because it was on sale. Also recieved Tropical pack from friend on my birthday, so I have 3 DLCs so far.
I might buy the Twillight pack on the next sale, I really want the bats for my Night House.
