I don't get the people who want to turn gaming into in fictitious dick measuring contest. I couldn't care less if you play every game on the hardest setting and shun anything that doesn't have an impossible setting. There is no shame in playing a game on easy or not having the patience to memorize a trial and error difficulty game like Battlekid. There's enough gaming variety for everybody and it should be to each his own.
If someone's whole gaming diet consists of just the popular stuff like Gears, Halo, CoD, GTA and the like I don't see why they wouldn't be considered gamers. They're playing games. Who am I to tell them how to have fun? I love the Dynasty Warriors line of games, I can't exactly judge.
