The game was fun at first but it quickly gets to the point where the grind becomes exponentially long and tedious. After playing just about every day for a few months, it got to where I could maybe level up 1 dino a week because the amount of coins needed to level up a dino was insane...I'm talking like 15,000-20,000+ coins each...which, playing on/off for a few hours a day, I was lucky to break 3,000 coins a day. Unless you have friends, you gotta buy coins, otherwise progression almost stops.
