I wonder if Elite technically passes the culture test though. Most of the game takes place in space with no story due to the sandbox nature and even so I doubt the story would be based in Britain or other applicable places.
Surely Elite would count simply because it represents the legacy of three decades of the UK gaming industry? Without people like Bell and Braben (and Mike Singleton, Jeff Minter, Pete Cooke etc.) would people like me have got off our backsides as teenagers in the 80s and picked up programming on the 8-bit machines, which subsequently lead to a career? Without Elite, and puzzling over how the heck you got 8 galaxies worth of stuff into a 32k space, I don't think I'd have cottoned on to the wonders of procedural generation, or open-world gaming?
OK, this historical link might be a bit nebulous to convey to our wonderful ConDem overlords, but worth a shot surely?
