Game Assembly is a website where you get paid with points for doing things such as trials, surveys, and many more, there are other like points2shop that do the same thing, but their prizes are too high and you can never get what you want quickly, but in GA, you can get points to redeem fast! These points can then be redeemed for many cool things, games, accessories controllers, headsets, and so on. You can also get Xbox live/point codes that are sent to your inbox, same for PSN card codes and Wii card points.
It's easy, free, and real, nothing is lost by trying, "nothing ventured, nothing gained"
If you want to get on this site (and believe me, you do) click the link above, under "websites"
