I think it depends on your definition of "hardcore", but there are alot of good software people who game well above average even if it is below the level many would consider "obsessive".

The best computer games have alot in common with software design as far as thinking about how a system works, planning for edge cases that could lead to problems/opportunities, and developing the patience to find which strategies pay off over a long period of time.

More than that, I often find that the most addicted hardcore gamers are people who are using that to replace the sense of purpose that work gives them, which means they're pretty hard working once they find a career they enjoy. Of course, then they might turn into a workaholic instead...

This a little bit of overlap, but I don't think there's significant overlap between gamers and software developers.

Writing code and playing a video are two very different experiences. Sure, you'll need to test the game, but testing games is not a fun time contrary to popular belief. And more important, the vast majority of software developers do not actually work in the video game industry. Most either work in systems development or make CRUD apps.
