I already rated your game. But i got some thought about this topic. Yesterday i took my roommate and we made a drinking game out of the rating.
1. One try for each player/game and whoever plays worse has to drink. So you realy have to dig into the game.
2. Both have to rate the game and for every topic where the two opinions differ: thats a drink for you two. That keeps rating as fair as possible and connected to the actual experience.
We rated 25 games+ in 2 hours and it was super fun. I will do this two more times this week looking forward to it.
Of course: You can also only track score and don`t drink. Drinking is bad. Keep it in control. ;)
And finaly: I´m a student and in a very comfortable situation. Not everyeone got my time and i will keep rating games randomly, so guys who does not have the possibility to rate as many games as i do, got the same chance to get ratings. But if you got less time than me: i think posts like this are a good solution.
