I always wonder what people strive to do. This is a pretty fun game, that really only takes about 20 minutes of my time each day except when there is a tournament.
My main goal is to have one of every creature at Level 40 (with the exception of VIP creatures) without having to ever spend any real money.
As of now I am very close to this. Just working on getting the last few Cenozoic hybrids and the current superhybrid, and then I’ll have everything.
So what is your goal? What motivates you?
