This week's Steam Weekend deal is
interesting:
Brink is free to play until 1PM PST today, and costs only $5 until 10AM PST tomorrow. I thought Brink was
pretty good in its own right, with a cool free running mechanic and a catchy future-pop art style, but most of that was wasted without a dedicated single player mode. This would be a good opportunity for anyone who was hesitant about the game.
