The postal service actually sent an empty truck to our office, just to load up all the packages and everything we were sending out Scott Miller 'If you want us to make a game for you,' they told Miller, 'you gotta pay us $2,000 to do it.' Miller practically punched the air, knowing he would have gladly paid 10 times that amount to publish id's first game. But the nascent id Software wasn't convinced of the merits of shareware.
John Carmack had blown Miller away with his demo of a smooth-scrolling platformer on the PC-a feat akin to distilling Super Mario in his garage ( id literally did that, too).
