I played this game years ago and I also returned back to this game and I think this game is a great game with a nice structure and it is not a must to pay for the game to play and proceed with progress.However it has been a long time since the game has not added a new world but it is still fun to get new plants and play new events and competing with players. I will give this game an 8/10 because it sometimes gets boring to play arena after you have finished the persuit which resets every week
