Not all games need a computer or a video game system. Long ago, before the Internet and broadband and (one assumes) wheels and indoor plumbing, gamers played games on tables. Card games, role-playing games, and strategy games were all played with pens, paper, cards, dice, and figurines. Plenty of gamer geeks still play those games today. I count myself as one of them.
Wizards of the Coast owns Dungeons and Dragons and Magic: The Gathering, respectively the largest tabletop RPG and collectible card game franchises ever. WotC recently announced the strangely named Gleemax, a social site focused specifically on the pen/paper/dice/card gamer crowd. Gleemax will bring together tabletop gamers of all stripes with game reviews, game blogs, friend lists, local event calendars, and other handy services. You'll be able to hunt for players/hosts for various role-playing, card, and miniature strategy games, and even find out if any game stores nearby are hosting tournaments or campaigns.
Computer gamers will be able to get in on the action, too. If you're not a fan of tabletop games, you can use WotC's new video game portal to find new independent strategy games and WotC's own online games, like Magic Online and the upcoming Uncivilized: The Goblin web game.
You can check out Gleemax.com for a preview of the site, though it won't really get going until its social networking features get rolled out in August.
