In our house there are 2 xbox360's, and Xbox one, a PS4, 4 laptops, 3 kindles, 6 iPhones (one even belongs to my 8yo), an iPad and even a couple of Nintendo DS's. No one is addicted. (Well, if you ignore my iPhone Mumsnet app habit!)
Some people cannot control themselves when it comes to many things, not just gaming. Some people are idiots about drinking. Some people turn into dicks over football, other sports or things like fantasy football. Some get obsessive over hobbies (I'm looking at you ebay obsessed BIL and you, online shopping addict Stepdad!)
Refusing to allow your child to play a console may very well isolate him somewhat from his friends. My 8 yo spent time yesterday playing on his PS4 with his school friends and the one who didn't have a working headset FaceTimed DS using their iPhones instead so they could still chat during the game. They all had a great time.
However, as much as we ALL love gaming in our house it does not come become re anything else. When I or DH say, "right, times up, turn it off", it gets done. We do compromise and allow them to play until the next save point or the end of a match though. We're not monsters 
When getting your child a bit of tech, do it with conditions. I'm happy to allow phones but even the teenager must allow me to randomly check her SM or phone when I require (which I never actually do except when I suspected her being bullied) In my house, when I say game's over, it is. I give no reason. DS is going tech free today because he had a lot of time yesterday and I feel he needs a break. Boy knows better than to complain, so has accepted it just fine.
If a child gets aggressive when told to stop gaming then that's more to do with the parenting than the console.
My friend's kids are limited on... well, everything. Tv is heavily monitored, screen time is timed. Kindles shut off at precisely 7pm and all internet access is heavily controlled. Even certain tv shows are not allowed to be on when the kids are in the room. On one visit DFriend asked me to turn reruns of Casualty off on the tv left on in the background as it was "a bit much" for children. They were 6 and 9. Quite frankly, the children are brats. Very naughty, very rude and not a pleasure to be around. The isolating from 'negative influences' has done the opposite.
