GTA 5 could be the most expensive video game out yet!

Turns out that Grand Theft Auto 5 could be the most expensive video game ever created in video game history with total development and marketing spend hitting £170 million , according to a new report.

Scottish newspaper The Scotsman states that "the game's development and marketing budget of £170 / roughly $265 million U.S. dollars" makes it "the equivalent of blockbuster films". Compared to Hollywood movies it comes second to Pirates of the Caribbean: At World’s End. The movie had a $300 million dollar budget.

Though the split between marketing and development hasn't been defined, if accurate, the launch budget pits GTA 5 as one of the most expensive games ever made.

In comparison, 2009 release Call of Duty: Modern Warfare 2 is estimated to have launched to a $200m (£127m) development and marketing budget.

The report also claims that GTA could sell 25 million copies within the first 12 months, racking up sales of £1billion. The total pre-orders is said to have received 2.5 million ahead of its September 17 launch on PS3 and Xbox 360.

GTA 5 is expected to break opening week sales records in the UK and the U.S.A., with first week sales expected to pass the 2 million milestone achieved by current record holder Call of Duty: Black Ops.

According to a previous report, UK retailers have been allocated a huge 3 million units for the game's launch next Tuesday, September 17.
