The quest system is genius. I'm an achievement whore, so this is awesome! I get to see what this site has to offer and I find things I'll otherwise wouldn't. I have never seen any other site something like this, but they should. Achievements have come to stay.  
 
Good hunting! 

I never thought of myself as an achievement whore, but I think I am now! Completing quests has led me to go back to older games and try to finish a couple unfinished achievements. Currently trying to S-Rank in Doritos Dash of Destruction, haha!
