To be a true gamer is to be eternally behind the times. Quite frankly, there's too much stuff out there to be a "true gamer" and be anywhere near caught up. Who honestly has time to really beat three or four open world RPGs, master 5 fighting games, learn the physics to a half dozen racing games, and platform your way to roughly 6 trillion gold *insert trivial gold colored collectable item here*s over a down platformers per year.

If you're up to date, you skipped about 3/4 of the games that other gamers will swear you deserve to die for not playing. I've long since given up trying to be a true gamer, it's nigh impossible without being an author for IGN or EGM.
