My guess is hardcore PC games are built with robust multilayer and replay options that have games develop cult followings while console games are usually more focused on other areas. Some PC games can be played for years. Console gamers tend to want a new game every month and PC/console games don't usually get developed in mind to have the lasting appeal for PC.
Example for me would be Diablo 2. It's 9 years old and the game is still very active and is a point and click game for the most part. If they brought D3 to consoles some people including me couldn't help but think the series would severely suffer in quality from it.
