what is gaia
Gaia Online is mostly just a giant forum, since that's where most of the action takes place. When you sign up for an account, you get to choose an avatar which you can dress with items from the Gaia Shops. You can earn gold by playing games or posting on the forums, and use the gold to purchase more expensive items for your avatar. It's a very addictive site for some reason.
gaia is like an online game the teens get to play games in and chat aka roleplay
it's actually called gaiaonline.com but there is also another thing called gaia which i never heard of i hope i've help you
its not so much games, i never play any of the games except jigsaw.
its more like a chat / myspace-esque type environment.
