Valve, creator of such popular titles as Portal, Half-Life and the recent Left 4 Dead, recently granted Game Developer magazine a list of lifetime sales data for their most popular titles.
The list, reprinted by Gamasutra, demonstrates succinctly just how successful Valve has been over the years. The original Half-Life alone has moved nearly 10 million copies -- and that's only including retail sales.
Valve remains tight-lipped on exactly how many copies their digital distribution platform, dubbed Steam, has sold over the last few years of its existence.
Though the Gamasutra piece examines the numbers and offers commentary on their significance, Shacknews was kind enough to boil the figures down to a simple bullet list. You can find the details below.
