Welcome to the official MEW One Hour challenge. The rules are simple: you have to play one random game from your backlog for one hour. After that one hour, come tell us about the game. At the end of your post, you can classify whether or not you will continue on with the game, or stop playing.
The purpose of this challenge is to try and get more people playing some of their older titles in their backlog. When they tell others about their initial experience, it may help us all to know which games we should or should not play.
Each week you only need to pick one game to play for one hour.
Edit: If you want a fully random picked game, try using the What Should I Steam website to pick the game you play (thanks @Blazzok) :
