Never Too Old
One of my favorite new gaming sites has got to be 2old2play - the Older Gamers Paradise. It's written specifically for the "older" gamer, which by their definition is 25 years or older.
They have a pretty active forum going, but you to be (or at least claim to be) 25 years old to join. They also have clans set up for lots of different games, a podcast, and a monthly magazine. The second issue of their PDF magazine was recently released.
The quality of this magazine is every bit as good as what you might find in a store. There are a couple articles that make this month's issue worth downloading for me - an interview with indy game developers Stardock Entertainment and a history of the Legend of Zelda.
The Legend of Zelda is probably the first game that I was really addicted to. Before Zelda, I played lots of games off and on, but once I discovered Zelda, I had to beat it. I played day and night. Then once I beat the game and started over, I realized that some places in the world had changed and I was hooked all over again.
So if you're old enough to remember the "good old days", check out 2old2play. Most gaming websites are filled with boys who have never kissed a girl. Here many of the members are married with children.
