This report conducted by Olsberg SPI on behalf of Ukie, the trade body for the UK's interactive entertainment sectors including games, was the result of consultations with over 40 stakeholders.
It calculates that 21m people play games in the UK, with 44 per cent of players being women and 22 per cent being aged 45-64. The industry comprises 1,900 games companies in the UK with 12 clusters across the UK and six further areas with critical mass.
Using work from Nesta, the innovation body, the report listed the cluster areas as: Brighton, Cambridge, Cardiff, Dundee, Edinburgh, Guildford & Aldershot, Liverpool, London, Manchester, Oxford and Sheffield & Rotherham.
The report sets out recommendations that could enable the UK games sector to contribute another £1bn annually by 2020. These cover areas such as funding, talent strategies, tax rules and promotion.
