Anything that I play long enough to feel like I have good feedback, I will usually rate. I also have noticed that I rate a lot higher than most on itch. If I pick something up and it doesn't grab my attention and I click off of the game in under 5-10 minutes, generally I won't rate it, but anything I stay on longer than that I try to have some sort of input on. I honestly don't play a ton of games on here, so I'll go weeks at a time without rating anything.
