The ARS(Achievement Rating System) has returned. This is Fafhrdd's tool that allows you to rate games you have completed by difficulty and time consumption. There are search functions to find easy games that you haven't played. Also, these are the numbers that show up in the badge calculator for each game. So please check it out if you haven't tried before. The more ratings that are made here will make the meta ratings for the games more more reliable.
Find it in the menu above under Games or find it here.
