thanks for your explanation! As there are so many games to look at and we can't see rates/reviews, I guess it's better to rate games using the "least rated" option?
It is definitely a LOT of games, but it's doable to rate them all. And ratings aren't guaranteed to be 5-star, so it's good to go after games you really want to see included. If you have time, you can go from there since you can filter out the ones you've rated already :)
