I suspect the UK tradition of bundling multiplatform titles into a single sales chart entity stems from the early days of videogames there, when the same title would often be released on a pretty broad variety of then-viable home computer platforms. Trying to parse out a title's overall market success in the Oric/Acorn/Amstrad/BBC/Sinclair/Commodore/Dragon era would have made the charts almost meaningless.
