The problem with labeling gamers hardcore is number one it just isn't true. Secondly it just makes you sound like a pompus selfapointed blowhard. I watch TV, am I a hardcore TV viewer? It might make you sound cool amoung certian circles, but mostly it makes you sound like a tool.
Now if you actualy look at the games you play, that most people play you are going to see a wide range of games. Maybe you play CoD, FIFA, Deamon Souls, and Plants vs Zombies. Does the last game on that list mean you forfit your hardcore badge? If when you get done with the new DMC, and then toss in Pinball FX2? What if you play Civilization V for 6 hours solid, and then a few rounds of Peggle before bed? Or Minecraft? Or Castle Crashers?
What if before you get home, to your ps3, on the train, you play a few games of something on iOS or Andriod? What if you do play a bit of Nintendo Land with friends and family on friday nite?
This notion that the game you play defines your value as a gamer is pointless and childish at least. A gamer is a gamer is a gamer. And most gamers like games across all different generes. It makes you a well rounded gamer, I think.
Look at Acti. Thier current and fading horse is CoD. The up and coming next horse they are trying to build up is Skylanders. My point is that the devs/pubs don't care what you play, only that they can sell it to you.
The word hardcore gets thrown around at each new gen. Each platform is paying lip service to the early adaptors by proclaiming that their platform is going to be a hardcore haven. And normaly the tools eat it right up. You know who thinks they are hardcore gamers? Fanboys. It makes them feel special.
The reality is that most people just buy and play what they enjoy. They don't care what someone on the internet labels the game or them. And most of us buy so called casual games right along side of so called hardcore games. Trying to make out a destinction between games is again just silly fanboy drivel.
Years ago there wasn't a whole lot of choices out there for gamers to pick from. Today there is and most gamers don't limit themself.
