It's a simplistic take. It lacks the subtlety of reality and denigrates gamers into two neat categories that don't actually exist.
I'd personally say that hardcore gamers do exist, but whether someone can be categorised as a hardcore gamer or not
isn't dependant on what sort of games they play and enjoy. It all comes down to how they play rather than what they play.
I consider myself to be a hardcore gamer because I play games to completion whenever I can, am
very competitive in both local and online play and most of the time, thanks to the industry going downhill and making games too easy these days, I don't use the likes of bullet-time etc and don't like to hide behind cover whilst my health regenerates - I tend to run and gun instead, rarely use ADS and always turn off aim-assist when possible. Running and gunning does tend to mess up the AI sometimes, I completed Killzones 2 and 3 doing that and there were a couple of times where I'd got behind the enemy and those Helghast fellahs didn't know what to do with themselves lololol.
For me, just about every game can be a hardcore game, it isn't the game it's the way you play it. Especially the likes of mini-game collections such as Wii Sports, Wii Sports Resort, Rayman Raving Rabbids and in particular Mario and Sonic At The Olympics.
There's a new trailer released by Ubisoft for ZombiU, I'll post it later if someone hasn't done so already...I'm playing catch up again lol. Looks like the lighting has improved a little further, AA is there and better ansiotropic filtering too. Pretty much what I was expecting given the difference in IQ between the E3 Nursery footage and the Comic Con footage not so long ago. Nice.
