I have a few of these free trial sites in my favourites and sometimes, (though not often), if you download a game from one site and time runs out you can download from another site and the history of the game is stored on your p.c. this allows you to carry on from where you had got to, admitted it's a bit tedious downloading every hour or so but it is cheaper than buying something you might get bored with after a few hours, if after four downloads and four hours of playing, it might just be a game that will keep your interest and be worth buying.
