It is something called a MMORPG, massive multi-player online role-playing game (break out your Dungeons and Dragons dice, guys!). Players create their hero or villain and are mentored by their favorite characters (like Batman, Superman, Lex Luthor, or The Joker) as they save lives / spread death and destruction all over the various ports of call in the game.
And at this house, we (mostly) love it. It's terribly addictive, I'd recommend it except that it can be the biggest brain-drain time-sucker you've experienced. As you level up your character you get more badass and can interact with the "heavies" of the DC Universe more. Which is dorky, I realize, but fun.
I also love video games. Not all of them, but some. I grew up with parents who resisted them, we eventually had an Atari and a Nintendo NES, later a Sega Genesis. In college, there were many times I'd sit at home with with my little brother playing Madden or Mario instead of going on a date or stepping out - it was fun to hang and goof off.
Nothing's changed much, except that sometimes I think I'm supposed to set a better example of responsible adulthood for my children than to sit on the sofa and geek out over games like this one. This is the source of endless household controversy, as the wife takes a dim view of video games.
My wife and I are about 40, and occupy a weird generational position. On the one hand, we were kids in the early days of home video games (with the Atari system), but those were days when games and gaming were less-advanced and far less immersive: you'd play a few levels and those levels were repetitive, the game exhausted itself within an hour or so at the most. As games progressed, that changed. And now, with the advent of online games, the gaming experience has expanded exponentially to the point of near-limitless gameplay.
As a result of maturing in this "gap" I've noticed that my peers (folks about my age) are split, some embrace new technologies openly and other seem to wish that we'd return to the halcyon days of "playing outside all day until Mom calls you in for supper" or "reading a book."
DC universe offers something like limitless play, though I'm not sure it's The Greatest Ever. Missions are repetitive at times, and that gets tedious. But the sheer number of different character types reduce the repetition. My son's hero is based on The Flash. My two daughters' on Wonder Woman and Batman respectively. And me, I'm the pal of the villainous Joker -duh. Sometimes it's just fun to splat the good guys with a huge boxing glove on a spring.
Like I said, my wife and I demonstrate the "split" I was referring to. She'd prefer our kids to get out of the house and explore the world. I can't really argue with that, it's a fun thing to do. But our kids (and perhaps this is my fault - being a lazy parent) seem to enjoy playing their video games more than chasing bugs outside. And yes, if you're wondering, I've fought with my kids over this plenty: unplugged the TVs, confiscated the games, etc. A healthy balance between "fun" and "obsession" needs to be found, most especially in a world where the video games are so damned addictive.
An older lady, a Eucharistic minister in our church, was talking to us a few weeks back at the local bagel shop. She mentioned that she played World of Warcraft with one of her sons (seriously, the last person I'd have expected to be playing that MMORPG). She said that, at first, she hated the idea. But, since her son lived across the country, she decided to try the game out as a way to connect with her son at his level - doing something he enjoyed. Over time, the game hooked her, too, and they apparently play it together every week.
I was struck by her story. You can try to force your kids to connect with you on a level that you decide that they should be connecting with you on....or you can (when appropriate - I'm not saying "anything goes" here....) try and engage them on their turf. In a world inundated with technological advances the choice is to embrace it or refuse it. My bet is that if parents don't embrace it their kids will.
I'm not saying I've got anything figured out, here at my little house - not at all. My preference would be for my little guys and gals to grow up healthy, get out and see the world, and do well in their studies - with video games being a pleasant diversion. For the most part, that's all they are (unless we're the 15-yr old....) And we're not lawless here, there are rules and we're in charge (for the most part). In the final analysis, it's merely one way to share an experience with my kids. I can live without the endless arguments between them about whose character is better than whose, though.
Because mine blows all their heroic asses up. With a smile.
