Google Play Store now asks certain game players to rank a title's gameplay, graphics and controls
The advantage to this is that it allows game players to leave more realistic ratings. Under the old system, you might have decided to buy a game that had a high ratings score only to find out that the graphics were poorly done. With the new ratings, the same game might score highly for gameplay and controls, but you would be warned to stay away from the game by a low score for graphics.
Those who already have the latest version of the Google Play Store that includes the new rating system will still be prompted to post an overall score, followed by their scoring for the three individual parts of the game. As usual, players are asked to leave a score between 1 and 5, with 5 being the best score that can be given.
