The review was led by psychologist Dr Tanya Byron, who was tasked with making children safer in the digital world.
Games currently receive a mandatory review by classifiers only if they contain "human sexual activity" or "gross violence".
Dr Byron is also expected to call for a UK body to oversee child net safety.
The review was launched last year at the request of Prime Minister Gordon Brown.
At the start of the review, Dr Byron told BBC News: "The study will be about what industry is doing already to protect children and what more could be done to ensure they have a positive experience on the internet and with games."
The review's publication follows a report by the Insitute for Public Policy Research (IPPR) which says many young people are effectively being "raised online", spending in excess of 20 hours a week using sites such as Bebo, Myspace, Facebook and YouTube.
The IPPR has called on the government to do more to protect young people from inappropriate content.
The think tank has called for an annual report produced by regulator Ofcom on the effectiveness of initiatives aimed at tackling harmful internet content.
The IPPR also wants Ofcom to police cross-industry guidelines setting out the limits of what young people can expect when on social networks and how to behave online.
More than half of all children surveyed by the IPPR reported they had come into contact with online pornography.
Dr Byron's report is expected to recommend cross-industry codes of practice which are independently monitored, on areas such as user generated content.
The review is also expected to recommend the creation of a website for parents where they can find out more information about online safety.
