I don't get new obsessions very often. I've had the same 2 games I've played (once, since 1999) and the other since 2004.
I dabble in other games once in a blue moon, but I always go back to my 2 favorite games.
Being autistic, I have a pretty limited scope of interests (all of my interests are actually listed in my diagnoses, because I have so few.)
So, getting a new one like the chickens, my husband encouraged because it encourages me to be social, leave the house, and do other things, like participate in 4h with my daughter for her chickens. LOL
I actually talk to grown ups about something besides kids now.
