Microsoft has a lot to gain from Grand Theft Auto IV on the Xbox 360, but there's one possible little problem. While Sony's PlayStation Network is free, the Xbox Live Gold service that allows online multiplayer is $50 per year. By and large 360 owners don't seem to mind the 4-per-month charge, but it could be daunting for newcomers. Maybe that's what influenced the decision to include a free month-long trial of Xbox Live Gold in every copy of the game for the Xbox 360.
