You know how you hover over a game in the New games, it tells you plays and the rest of it but it doesn't say the rating, could it be possible to have it like:
Name Playes [8.5/10}, I know its something little but its pretty useful
Well, it could possibly be like that so you play the game instead of judging the game by the rating.
In other words, if you see a game with a rating of 4/10, you wont play it because you will think the game is bad even though you haven't played it. If you see a game with a rating of 9/10, you will automatically play it because you think its a good game.
In short, it may be a way of making sure all games get played instead of just the popular ones.
