The game is still fun so it deserves a high rating, however its not exciting anymore for longtime players. Im definitely not playing as much as I used to. My original goal was to fill my Pokedex so hunting for new Pokemon and hatching eggs was fun. My husband and I would also drive to new parks and places to find Pokemon and battle gyms together. I initially invested some money to buy coins but with so many high CP Pokemon, I was easily staying in multiple gyms for days and collecting coins to buy incubators. Now, my Pokedex is almost full, eggs are not hatching anything new so theres no incentive to buy coins, theres no incentive to join multiple gyms b/c of the daily coin limit, and theres no incentive to power up your Pokemon since a) your CP doesnt matter in a gym since it goes by when you joined and b) since your coins dont accumulate, the idea now is to put something weak in a gym so you can get kicked out within the day. Since CP isnt really important, theres no incentive to get more stardust either (and therefore no reason to spend money on incubators to hatch eggs). So for me, Im just riding the game out until the next gen is released and enjoying my increased productivity with the rest of my life :)
