Game developer, fiance and new father here, I definitely can weigh in on this. I'm guilty myself of going straight to the computer when I get home to play some games and unwind. I'm lucky enough to have a partner who also is a gamer, but even then at times too much gaming is definitely a very real thing.

When you come home from a long day of work you want to unwind. For some that's watching TV, reading a book, having a few drinks, ripping a bong or playing some games... or some/all of the above. When you're gaming your mind is temporarily transported to a world where bills, debt and stress from that stupid thing your boss did earlier don't exist. You're freed from the weight of responsibility and it's more than easy enough to lose yourself in there for hours at a time. On top of all that gaming offers much more that could be a whole post on its own (and probably should be).

The damage comes when it's the everyday grind and it detracts from regular healthy activity and time with your friends and family. A balance needs to be found for every unique person.
