An independent report on the games industry in Ireland reveals the number of people working in the sector has almost doubled since 2009.

The Irish Computer Games Survey 2012 also says there are nearly four times as many games companies here since the time of the last major report on the industry three years ago.

The report identifies 83 companies operating in Ireland today. That compares to 21 companies in 2009.

It says these companies employ 2,802 people - an increase of 91% since 2009.

The report also shows a large increase in the number of game developers within Ireland, particularly in the Leinster region.

It identifies 51 separate game development teams - up from 13 in 2009.

They are working across 12 different platforms, with development centred on the iOS platform.

The report says the surge in the number of indigenous developers in Ireland has "assisted greatly" in providing new jobs.

But it stresses that the continued expansion of international companies here "has equated to the vast majority of the additional roles".

The report estimates the sector generated over €2 billion worth of sales between 2001 and 2011, with the 2011 market value estimated at over €211m.

The Irish Computer Games Survey 2012 has been compiled by Jamie McCormick, Marketing Systems Manager with Dublin based GALA Networks Europe, with input from by Dr Aphra Kerr of NUI Maynooth and Dr Phil Bourke of LIT Thurles

They say it offers a benchmark against which future growth in the industry can be measured.

The publication coincides with the launch of the Science Gallery's new show, GAME, which explores the future of gaming.
