Nah, I don't think games have ever become unhealthy for me.
There are times where I've felt I've spent too much money on games, but it's never been at the expense of bills, necessities, or savings. Usually it's just a 'I probably should have saved more than the planned amount instead of buying a game', or 'I should've bought something else instead of another game.'
As far as socializing, I think games help me talk to people just as much as keep me from it- and the situation matters. I don't think playing a handheld waiting at the DMV instead of chatting is bad, for example. Plus, I've struck up many a conversation about games with classmates/coworkers/customers/other shoppers over the years, aside from people met at gaming events- it works out.
Health is the only one that, at surface level, seems like an issue. I am certainly a fairly sedentary person with my gaming habits... but here's the thing: if/when I don't game? I sew, and craft, and read, and watch movies & Youtube. I'm a sedentary person in general, really. Removing gaming from the lineup isn't gonna result in me taking up jogging or anything. Yes, I need to exercise more... but it's not a gaming problem, it's a 'me' problem.
