Free gamez plox

Have fun.
By the way, some of the games may no longer be free, however at the time I compiled this list they were. Whether they were in Beta, or the developers simply felt they could make some money with their product. Older versions of some of the games now being sold can however still be downloaded and played legally as far as I know.
