Today is Britain’s perhaps most thrilling day of the year. It’s the day that the Chancellor of the Exchequer gives his Autumn Statement, the annual not-quite-the-budget about which everyone has been on tenterhooks for weeks. Will he make being unemployed entirely illegal? Will he announce that all benefits claimants must be his butler for one day of the year? Will he demand that the disabled must either stop complaining or move to Russia? Probably, I don’t know – I was playing Far Cry 3 over lunchtime. But one thing he has announced is a 25% tax relief for UK games developers.
