I realized the other day that I hadn't rated a game on the AppStore in a long time and I need to change that. I think the problem is that I never pay attention to AppStore reviews when I make a purchase. Too many people give one star reviews because it's not free or because it is free but has ads in it and I just don't trust most of them. I always come here to get impressions or read a review and then click on the link to buy the game. Even though I don't personally read AppStore reviews, I know that they are important to the devs so I'm going to make a concerted effort to rate every decent game I play to support them.
Honestly, only when the I can give critical reception on the game; be it very good criticism or very constructive criticism. And of course when the game is a scam so I can give forewarning to any one else buying it.
