I see words like "learnt" rather than "learned" and dates as DD/MM/YY rather than MM/DD/YY. I'd think that would make this the British version, but unlike most PAL games I don't see a language selection. Also the developer is British, so maybe the American version might not have have altered the spellings. By the game clearly takes place in Not New York, so the spellings should have stayed in American for immersion.
