> Valve should never have shipped a 32-bit application in the first place.
It's literally a 2004 game! That's ridiculous. A handful of opterons existed in the market, but Intel wouldn't get there for years still and it was well over a decade until x86_64 crossed 50% market share in consumer stuff.
Good grief, as it were.
In 2004, sure, but Valve didn't (publicly) ship Mac OS X software before 2010.
